SHENGYUAN INDUSTRIAL AND MINING CO., LTD. Shengyuan Industrial and Mining Co., Ltd. is located in Dawan Town, Zhongshan District, Liupanshui City, and was established by reorganizing the assets of the former ShuiCheng Mining (Group) Company Muchonggou Coal Mine. The company's shaft field covers an area of 17.4 square kilometers, with abundant high-quality main coking coal. The design of the mine was completed in March 1966, with a capacity of 900,000 tons of raw coal per year, and it was put into trial production in October 1974, with a service life of 79 years. The mine adopts zoned extraction ventilation, centralized ventilation in inclined shafts and flat caves, and centralized return air in the return uphill. 1800 flat caves are transported by battery locomotives in the big alley, and there is a light ground railway of 1520 meters to the coal bunker in Dawan. The company has invested nearly 100 million yuan of state bond funds to renovate the mine's gas monitoring and ventilation, extraction, power supply, hoisting and transportation, drainage and other safety facilities (systems), and now has one production mining area (four mining areas) and one succession mining area (three mining areas), with the degree of mechanization of coal mining and digging reaching 100%, one set of integrated mechanized coal mining unit, three integrated mechanized digging units, and nine sets of gas extraction systems, There are 9 sets of gas extraction systems, 1 set of KJ90 safety monitoring system and Advantech PIII monitoring center station as well as mining explosion-proof fiber optic camera, the mine's overall anti-disaster preventive capability is strong.
Dahebian Coal Mine Shuicheng Mining Group Company's Dahebian Coal Mine is located in the territory of Dahe Town, Zhongshan District, Liupanshui City, the mine is designed as a sloping shaft development, in December 2004, Guizhou Coal Administration approved the mine's production capacity of 900,000 tons per year. The products of Dahebian Coal Mine are washed coal and screened coal. The coal quality grade is gas coal. The industrial indexes are high volatile matter, high calorific value and medium-low sulfur. It is the main upstream product of electric power, metallurgy, building materials, chemical industry and other industries. The products are sold to the province and Guangxi, Guangdong, Hunan, Hubei and other places. Due to the special nature of industrial index, its products have been favored by all kinds of users. Dahebian mine is developed by a pair of inclined shafts, divided into 3 mineable levels along the incline, and designed*** with 12 mining zones. The mine design adopts long-wall backward coal mining method, and the working face of coal mining successively adopts logs, metal friction pillars and monolithic hydraulic pillars to support, and all the trapping method to manage the roof.In 1974, we tried to mine coal with MDQ-80 coal mining unit in a mining area, and because of the large inclination angle of the seams, the coal quality is hard, and the bottom plate is soft and slippery, the unit stops working after half a year of trial.In 1992, we used MG200-W high-grade coal mining unit to mine coal with MG200-W, which is the most powerful coal mining unit in China. In 1992, MG200-W type high-grade general mining unit was used, and in May and July 2008, comprehensive excavation and comprehensive mining were installed and used respectively. Raw coal is lifted from the skip of the main shaft to the coal bunker on the ground, and the gangue is lifted from the secondary shaft to the gangue mountain by a trolley.
