The first summary of personal work in mechanical and electrical specialty passed quickly, and it slipped away in a hurry after more than XX months unconsciously. Looking back, there are gains and shortcomings in electromechanical work. Focusing on the policy of safe production, we conscientiously implemented the "Coal Mine Safety Regulations", put people first, keep pace with the times, pay close attention to management, and basically realized the safe, installed, stable, economical and efficient operation of the electromechanical system. Through this past work, we have accumulated a lot of work experience and greatly enriched and improved in all aspects. Now we will make a summary report on the electromechanical work.
First, based on safety laws and regulations, strengthen the standardization of electromechanical safety and quality.
Standardization of safety quality is the fundamental way to improve the level of coal mines and build a long-term mechanism of safety production. Only when the standardization of safety and quality reaches and maintains a certain standard, and the enterprise is in a good state of safe production, can it adapt to and guarantee the life safety of employees and the needs of coal industry modernization. Starting from March, with the worst conditions as a breakthrough, the construction of 22 10 centralized transportation lane, substation in the second mining area, electromechanical equipment in the mining area and cable hanging standards has started, which has promoted the new climax of quality standardization construction in all regions of the mine. Through standard appraisal, * * * was rated as 3 "boutique clubs" and 2 "boutique computer rooms".
Second, the mechanical and electrical work completion
Since 1, the Ministry of Machinery and Electricity has been focusing on the goal of creating a standardized "Xinzhou Demonstration Mine" for safety and quality. The substation in the second mining area has been transformed into a standardized chamber, and the layout of high and low voltage equipment in the substation has been refined. High and low voltage power cables and lighting suspension have been "linearized". A new plastic cable hook (398 1) was replaced, and standard high and low voltage cables and signal cables (597 1.5m) were laid. Underground cables are hung horizontally and vertically in a line. After the transformation, the underground electromechanical chambers, alleys and mining areas have formed a new bright spot project, which has improved the underground standardization level.
2. Due to the limitation of geological conditions, the output of 6.5438+0.8 million tons makes the installation of fully mechanized mining equipment and the transformation of power supply system in coal mining face become the key projects for safe production. In the whole year, the fully mechanized equipment installation, water supply and compressed air system installation and power supply system transformation were successfully completed in five working faces: 22 13 working face, 2200 working face, 2XX0 working face, XX03 working face and 22XX working face. And successfully completed the 22 13 working face, 2207 working face, 2209 working face, 2XX0 working face and 2200 mining working face, and realized the safe production of all-round communication and all-round power supply.

(4) Pipeline installation project of water supply and rescue system: underground fire sprinkler and water transformation in Xiliang, where water is supplied by a 600m3 static pressure pool on the ground in Xiliang District, and the original water supply pipeline φ502.5 seamless steel pipe 2 130m is removed. Φ1594.5 seamless steel pipe is used for the perfect laying of underground water supply and rescue main pipe, and φ 1084 seamless steel pipe is used for mining area and downhill pipeline. At present, the underground main pipe φ 1594.5 seamless steel pipe is laid for 3,550m, and φ 1084 seamless steel pipe is laid for 480m.
(5) Installation project of 35kv substation: The erection of the ground 35kV substation in Xiliang District has been completed, and its two 35kV power supply lines are led out from XXKV substation of Xuangang and XXKV substation of Fuyang respectively, with conductor section lgj- 185. The line length is about 18.5km and 26.5km Except for two SZ10-8000/3535 32.5%/10.5kv8000kva on-load voltage regulating transformers in the substation, other high-voltage electrical equipment in the substation has been installed.
Three. Completion of transportation work
1, for the purpose of serving the front line, to ensure the continuity of mine production and the completion of production tasks;
The transportation system safely and efficiently completed the transportation of dismantling and installing equipment in five working faces, and transported more than 2,520 sets of large equipment such as hydraulic supports. Over the past year, we have laid 2570 meters of 18 kg track and XX00 meters of 24 kg track for the mining area, ensuring the completion of the production task of the whole mine and the normal production of our mine.
2. Take standardization as an opportunity to continuously improve the level of safe transportation;

For the existing power supply system of our mine, there will be several major renovation projects this year, such as the installation of transformers in 35kv substations, the installation of overhead lines in Xiliang District 10kv, the renovation of overhead lines in Gaobaowan 1 loop, the installation of equipment in underground substations and mining substations, the laying and installation of underground power supply lines, the main ventilator, the central water pump room, the central substation and production.
Summary of Personal Work of Mechanical and Electrical Specialty Part II As a technician in the power supply workshop of Mechanical and Electrical Department, based on my post, I pay attention to mastering my own power supply system business, improving my technical level, actively participating in various trainings, constantly expanding my knowledge, applying advanced technology and combining my own professional knowledge, and applying power supply technology to coal mine safety production.
First, actively learn technology and strive to improve their professional level.
In July, 2006, under the leadership of relevant departments, I went to Jiyuan Explosion-proof Equipment Factory in Henan Province to investigate and study, master the new technology and new process of new equipment, and actively discuss and communicate with my peers. Subsequently, relevant technicians from manufacturers and Nandian Chen Guo were invited to our mine to provide training on the application and maintenance of electrical equipment for power supply workers, and gave technical guidance to relevant technicians of our company on the spot, which solved many technical problems. I recorded the problems I encountered in my usual work and asked the masters in the power supply workshop until I understood them. Whenever the relevant technicians from the factory come to the mine to solve the major equipment failure, I actively seek their advice. Through continuous study and practice, I gradually became familiar with the application of underground power supply system and high and low voltage equipment, and improved my professional level.
Second, reasonably design the power supply system and scientifically formulate technical measures.
Under the guidance of the section chief in charge of power supply, I gradually designed the power supply system of each coal mining face. Because I am not familiar with the working face and its mechanical equipment, in order to arrange the route of high and low voltage cables reasonably, I often go to the scene, measure the distance, set up calculations scientifically, and choose electrical equipment and cable models reasonably, which not only meets the actual needs, but also saves a lot of manpower and material resources. I designed 8 17 1, 7 198, 7 196, 7 174(2), 8 172, 7 199, etc.
Based on the principle of "one project, one measure", I will formulate technical measures for construction safety in advance, strictly organize and scientifically formulate them, in addition to the maintenance of high and low voltage electrical equipment twice a month, as well as the laying or recycling of high voltage cables, equipment installation and standardization, so as to make the safety technical measures scientific and operable. After being approved by the leaders of relevant departments, it will be communicated to each construction worker, and signed before construction, and strict measures will be implemented, so that the measures can really play the role of supervision and guidance in the whole process of prevention. In addition, I also assist the workshop director to make equipment maintenance and material plan, and put forward technical measures to prevent electromechanical accidents.
Third, the task of safety and quality standardization has been fruitful.
In order to implement the quality standardization work issued by the mine, according to the situation that the power supply team arranges and hangs cables in the main tunnels and substations underground according to the standardization requirements, this paper puts forward reasonable suggestions and formulates scientific technical measures for safe construction. In 20 15, I mainly participated in the following major projects: Ⅱ (3) the installation of the upper substation in the mining area and the laying of its power supply lines; Installation of belt electric control system in belt concealed inclined shaft: Dongsan and Donger (3) installation of electric control and signal system of frequency conversion winch in mining area; Installation of power supply system in underground 8 17 1, 7 198, 7 196 and other coal mining faces; Installation of power supply system of large-scale fully mechanized excavator in -750 heading face: installation of power supply in -750 line workshop and transformation of power supply system of mining team; Main shaft substation replacement transformer, etc. By participating in these large-scale projects, I guided the technical work and further studied, laying the foundation for better power supply in the future.
Four, do a good job, improve the skill level of workers.
In daily work, according to the changes of the upper and lower high and low voltage power supply systems, the power supply system diagram is revised in time, so as to know the load of each substation at any time and be responsible for the maintenance of the underground remote monitoring system. At the same time, I recalculated the setting parameters of the high-voltage relay protection device in the mine and counted the high-voltage and low-voltage cables in the mine. Under the guidance of system leaders, we organize electricians to carry out skills training from time to time, learn new technologies, improve theoretical and cultural level and operational skills, and often organize skills competitions, and actively carry out activities such as "QC group" and "finger dictation operation method". Through these training activities, the professional level of workshop electricians and their ability to deal with switch faults have been continuously improved, which has greatly shortened the time to deal with accidents and effectively guaranteed the safe power supply of the whole mine.
With the help and guidance of my leaders and colleagues, I gradually became familiar with my business and made some achievements in my work, but I also knew my own shortcomings, such as my lack of experience in accident handling. Therefore, in the future work, I will strive to guard against arrogance and rashness, accumulate experience and lessons, constantly adjust my way of thinking and working methods, hone myself in practice, be strict with myself, constantly learn and innovate, live up to the trust of mine leaders and branch leaders, and strive to be an excellent technical personnel and make more contributions to the development of the mine.
Summary of personal work of mechanical and electrical specialty Part III is busy at the end of the month. Looking back on the work process in the past month and summing up the experience and lessons in the work in the past month, I realized the dedication and care from the leaders, and also learned diligence and self-discipline from my colleagues. Busy and full is the biggest experience in my work.
Through repeated inspection and acceptance by various departments, I have exposed many technical problems and low-level mistakes that need to be rectified. This pointed out the direction of improvement for me, and correspondingly urged and improved my overall level, improved my working ability, strengthened my sense of responsibility, and completed my personal work in time.
Not long ago, the work of developing three teams of electromechanical technicians was just started, which requires quite high quality of technicians in all aspects. I must devote myself to my work with a rigorous working attitude and a stronger sense of responsibility. Now I'd like to make the following statement about my work plan in Vanguard:
First, do a good job in the construction of safety culture and carry out in-depth professional team building activities.
Further establish the concept of safety first, prevent complacency and paralysis, take the spirit of zero starting point, take the past as a mirror and take the past as a driving force, do a good job in safety every day, every moment and every minute in the future, constantly cultivate positive factors in corporate culture, and refine and form a professional spirit that leads the development of enterprises with professional ideals, professional attitudes and professional responsibilities as the main contents.
Second, adhere to the people-oriented principle and strengthen the education and training of all staff.
Call on all employees to make piecemeal accident prediction, aiming at improving the overall safety level through employees' thinking. In order to realize * * * resource sharing, the typical mine cases are compiled. The case set is rich in content, and some cases and phenomena are usually not understood and valued by the employees. However, if we don't enjoy resources, we can learn from the past in time and others will repeat the same mistakes. On Mondays and Wednesdays of each month, the cases that happened in previous years this month are told to employees, so that employees can study and understand them seriously, improve the quality of all employees through learning, realize the safety of all employees, and finally realize the mine safety. The existing personnel will be optimized and adjusted according to the post requirements, so as to ensure that all post personnel meet the post requirements, continue to carry out safety education for all employees, and continuously improve the technical quality of employees.
Third, actively carry out hidden dangers investigation and management activities.
Before entering the construction site, the team leader, safety officer and team leader are required to conduct safety inspection on the working face, carefully investigate the potential safety hazards existing on the site and deal with them immediately; In the class, the team leader, the safety officer and the team leader conduct safety inspection on the working face again to check the work progress, whether there is any phenomenon of empty roof operation at the scene and the support quality. After work, the team leader, safety officer and team leader shall conduct safety inspection on the working face again, check the completion of the engineering quality of the working face, whether there are hidden safety hazards after work and safety matters that need to be paid attention to at the scene, and hand them over to the next shift to ensure safe production.
In the future work and study, we should improve our professional knowledge, enhance our sense of responsibility, and make contributions to the leap-forward development of Yue Chang. I should try to do: first, strengthen my study and broaden my knowledge. Study hard on professional knowledge and related experience, and consult experienced people such as leaders and colleagues. Strengthen the understanding and research on the surrounding environment and the development of the same industry, and know your own advantages and disadvantages; Second, in line with the principle of seeking truth from facts, actively do your own job without delay; Third, abide by the company's internal rules and regulations, safeguard the company's interests, actively create higher value for Yue Chang, and strive to achieve greater work results.
