Major coal mining on the 3rd. 3 coal seam buried in shallow, low gas content. Spontaneous bustion of coal at all levels is not strong, spontaneous bustion of coal is not easy. The design of the target coal seam is on the 3rd. Mine industrial reserves of million tons, recoverable ii reserves of 164,317,500 tons. Mine design capacity of million t / a. Coal on the 3rd floor meters thick, 35 degree angle, about 160 meters from the ground. Focus on the use of inclined to open up the way roadway. Along the mine field to the three main roadway layout, the track roadway, transportation roadway layout under coal seams in the rock on the 3rd, the wind back to the 3rd Lane along the coal seam floor layout. Mine the transfer of production capacity to meet the design of drilled shaft 3, that is, Lord, Viceinclined, return air shaft. The main belt inclined shaft installed, the Deputy Shop inclined orbit. The transfer of the total mine production for a twoyear period. Industry Square is located in the central mine. The No. 3 coal mine is divided into four mining areas, with a zonetype preparations. Designed with inclined longwall coal mining method. Extraction process using backstyle, integrated mechanized sublevel caving mining method. Operating system as system 46, three coal mining, a group of maintenance. Equipment face a doubleside doubledrum shearer adjustable, hydraulic support, flexible scraper plane, broken machines, etc. are reproduced. Goaf method make use of all crossloading roof management. Transportation Roadway mine used as a main transport belt transport track roadway tub used as a supplementary transport, ventilation tied for the central ventilation. Mine the total wind capacity of / s, the main fan for the work out of style, fan model: , n = 740r/min, electric power is 390KW.
