Coal mine is a reasonable space excavated by human beings in the excavation of geological layers rich in coal, about the coal mine work reflection What to write. Here is my reflection on coal mine work for you, I hope it will help you.
Coal Mine Work Reflection Part I
Dear ____:
A place where two coal mine mega water penetration accidents occurred within a month, resulting in 123 people trapped in the well, the survival of the coal mine accidents with little hope of survival, to the people's lives and property to bring great losses, and at home and abroad to create a very bad impact.
This fully exposed the safety supervision work on the more loopholes, in particular, did not fulfill the responsibility of supervision, the accident investigation and handling is not strict, rectification is not strong, the production safety law enforcement is not strict, the work is not practical, supervision is not strong.
In the face of irretrievable miners' lives, we feel very sad. Here, we to the State Administration of Work Safety and the State Coal Mine Safety Supervision Bureau to make a profound review.
A city of two consecutive coal mine water penetration accidents, there are three important reasons for deep reflection:
First, the complexity and severity of coal mine accidents is not enough to recognize. A city coal mine for many years in a row did not occur particularly major accidents, especially in the first half of this year did not occur a death of more than three major accidents, and then produced a paralyzing thought. In the first half of the year, a city provincial safety supervision bureau's main focus on the prevention and control of high gas and gas protrusion in coal mines, coal mine flooding has not attracted great attention. At the same time, that a city is a small coal-producing province, "should not" have a big accident.
Second, the grassroots work supervision and guidance is not effective. Xingning City, Fusheng coal mine "7? 14" after the water accident, a city and province to quickly carry out accident investigation, issued a notice of accident, a city and province Safety Supervision Bureau to the provincial government according to law to close the Xingning City, Siwang Roach Mining District, under the flooded area, including the Daxing coal mine, including the six pairs of mines. However, due to the lack of timely follow-up and in-depth grass-roots, resulting in the suspension of production rectification requirements have not been truly implemented, and ultimately lead to a particularly serious accident.
Third, the issuance of safety production licenses is not strict. Mining license is a prerequisite for the safety production license, but most of the original mining license of a city coal mine expired. A city provincial safety supervision bureau on the one hand, worried about the completion of the work progress issued by the state, on the other hand, worried about the cause of a considerable part of the coal mines due to the inability to receive the license to stop production, thus bringing negative impact on the local economic development and social stability. In order to accelerate the progress of licensing, after consultation with the Provincial Department of Land and Resources, it was clarified that the land department at or above the prefecture level could be regarded as having a mining license if it issued a certificate that it was in the process of obtaining the license. Accordingly, Daxing Coal Mine has obtained a safety production license without formally obtaining a mining license.
As a result of the weak legal concept, the pursuit of licensing progress, ignoring the licensing process, in the case of coal mining enterprises mining licenses and business licenses are not all the case, to take a "workaround" to the coal mine enterprises issued a safety production license, the gatekeeper is not strict, resulting in a major disaster.
Coal Mine Work Reflection Part II
Dear Mine Leader:
Regarding the recent workplace accidents that occurred in my team, the mine has come to a serious after the face of this accident I feel very sad, the accident has given me a painful lesson and prudent warning, fully proved that I have not been able to do the job in terms of safety. In this accident occurred a major original, is my work did not keep up with the leadership of the safety concept, did not put the leadership of the safety measures into practice, the beginning of my team did not create a good safety atmosphere, the accident did not occur because of a moment of negligence, not pay attention, is in such an unsafe environment, which led to today's results.
The accident has occurred, the future should be how to deal with, strictly prevent the occurrence of various types of accidents, reversing the team's bad safety atmosphere, not let our miners' blood flow in vain, this is in front of my team must be immediately resolved a difficult problem, the real mine's safety culture concepts penetrate into the minds of each employee, awareness, behavior; truly essential safety, I am determined to work in the future! Should learn from the lessons of the accident, the pressure into the work of the power to do the following:
1, unified ideological understanding, adhere to the "safety first" thought unshakeable, in the safety and production to deal with the relationship between the two, the two complement each other indispensable to emphasize the safety, highlighting the security, the safety of all the work in the first place, arousing our The first thing to do is to emphasize safety, highlight safety, and put safety at the forefront of all work, and arouse the awareness of each of our employees that "violation is an accident, and an accident means death", so that they can do a lifetime of coal mining and be cautious for the rest of their lives.
2, give full play to the role of the pre-shift meeting, increase education, training efforts, for our team of various positions, the sub-trade training, the new workers to implement the teacher to take the apprentice, to do a good job of passing on the role of the role of helping to improve the operating skills of workers. Increase the training of new workers, old workers and backbone employees. These employees have low safety awareness and safe operation skills, there is adventurism; old workers with old experience, old habits of illegal operation is y rooted; and some backbone both play a positive role, with into the regular violation of the rules, undermining the safety environment.
3, to do a good job of all kinds of hidden trouble, preventing trouble before it occurs, strict quality control of the scene, checking the hidden trouble to be meticulous, never let go of any small problem, dealing with hidden trouble to be decisive and thorough, and never let the machinery and equipment with disease operation. Establishment of a sound and perfect production management system, job responsibility system and operating procedures, strict implementation of the rules and regulations, in the work of the standard work, standardize their operating behavior, in order to make everyone's safety is guaranteed.
4, strengthen the training and education of the team leader, the team leader and the site of the work of the closest combination of the team leader to perform their duties to a large extent is the degree of performance of a district team embodiment of the level of the team leader to grasp this level of capture the scene, to seize the management, to seize the norms. To strengthen the training of the team leader, there should be a standard of work, to have training standards, to make the team leader level and our management of the trend and road, the formation of identity, and through the team leader will be our management of the effective radiation amplification.
5, to strengthen the quality of the followers, take the class, increase the hidden danger of self-correction. Each class organizes a good pre-shift meeting for the workers on duty, arranges for production tasks, safety precautions, and after the class seriously summarizes and analyzes the deficiencies and gaps in the work of the class, and improves and perfects them.
6, adhere to the pre-shift meeting of each class, to understand the production situation of the underground scene, do a good job on-site handover, confirm the work around the source of danger, the equipment inspection in place, and timely detection of hidden safety hazards and organization of the team on duty or vice-captains, nip the hidden trouble in the bud. Do not produce without safety.
7, often study, reflect on the relevant accident cases, enhance the team's awareness of accident prevention, improve the quality of safety hazards prevention and self-protection awareness, pay attention to the identification of various types of sources of danger, early discovery, early elimination, do prevention first.
9, really the accident lessons touch the depths of the minds of each cadre and staff, the concept of safety culture is really set up, so that workers from the behavioral dynamics to achieve the norms of the standard, do not violate the rules of operation, in order to make the workers to ensure the safety of production.
In short, to use the lessons of blood to arouse the consciousness of each employee to protect life and cherish health, to educate each employee can not violate the rules, can not figure fluke, afraid of trouble, in accordance with the standards, in accordance with the norms, and actually grasp their own safety, the formation of a wide range of recognition, to achieve the whole **** know **** enjoy. So that everyone realizes that grasp safety is for their own, is for their own family happiness, prompting the whole staff from the heart to enhance self-protection awareness. To do alarm bells always ringing, warning hanging high, around the mine leadership safety management concept, to do cognitive high, work fine, implementation of strict, and continue to promote the mine's safety production flourish.
Coal mine work personal reflection three
Coal mining methods are many types, the world's major coal-producing countries use coal mining methods, the general division for the wall and pillar type two categories. These two different types of coal mining methods, both from the coal mining system, or mining process are very different. According to different geological and technical conditions of the mine, there can be different coal mining system and coal mining technology, thus constituting a variety of coal mining methods. For example, under different geological and technical conditions, longwall mining method, pillar mining method or other coal mining methods can be used, and longwall and pillar mining method in the coal mining system and coal mining technology is very different. This can be considered: coal mining method is the coal mining process and back to the mining roadway layout of two parts.
1) wall mining
Wall mining method wall mining method is characterized by a long coal wall, the face of the two ends of the roadway were used as air inlet and air return, coal and material transport, mining coal parallel to the direction of the coal wall out of the face, China's wall mining method of mining coal seams.
2)Pillar miningPillar mining is characterized by a short wall of coal in the shape of a square column, the number of faces mined at the same time is more, and the mined coal is transported perpendicular to the direction of the face.
3) Water conservation coal mining with the concept of water conservation coal mining drew China's first planning map to control the ecological water level of coal mining methods, but also will become China's future guidance in the northwest water-scarce areas to achieve the coordinated development of coal mining and the ecological environment of the important scientific basis[2] .
Other mining methods
1. Toward the longwall mining method, the longwall working face along the direction of the advance of the coal mining method.
2, inclined longwall mining method, longwall face along the inclined advance of coal mining methods.
3. Inclined layer mining method, the thick coal seam is divided into layers along the inclined face.
4, longwall top coal mining method, mining more than 6 meters of slow incline after the slow incline of thick coal seams, first mining out the coal at the bottom of the coal seam longwall face, and then immediately release the top coal mining method.
5, cover bracket mining method. In the sharp inclined coal seam, the coal mining face is arranged along the strike direction, and the cover bracket is used to separate the mining area and working space, and the coal mining method is pushed forward to the downward inclination.
6. Pseudo-tilt flexible cover bracket mining method. In the sharp inclined coal seam, pseudo-inclined arrangement of coal mining face, with flexible cover bracket will be separated from the open area and workspace along the direction of the advance of coal mining method.
7. Inverted step mining method. In the stage or section of the sharp inclined coal seam, the lower part of the step-shaped working face is arranged in front, and the coal mining method is advanced along the strike.
8. Positive step mining method. In the stage or section of the sharp inclined coal seam, the coal mining method is arranged in the pseudo-diagonal direction to form the upper overrunning step-form working face and advancing along the strike direction.
9. Horizontal layer mining method. The coal mining method of dividing the thick coal seam into layers along the horizontal plane.10. Slant cut layer mining method. The mining method of dividing the coal layer along the slanting surface which is 25 degrees to 30 degrees from the horizontal surface in the thick and sharp slanting coal seams.
11, room and pillar mining method along the roadway every certain distance first mining coal room until the border, and then back out of the coal room between the coal pillar mining method.
12, room-type coal mining method. Along the roadway every certain distance to open the coal room, between the coal room to retain the coal pillar to support the roof mining method.
13, storage mining method. The coal will be temporarily stored in the mined space in the sharply sloping coal seam, and then released after the coal body in the warehouse is mined, the coal mining method.
