Embodiment Construction
[0064] An integrated coal mining method for coal mining and filling includes the following steps:
[0065] 1) In the mining area, develop the return air and fill the pipeline lane 1, the transportation and intake air lane 2 and the boundary air lane 3; the three roadways are connected, and there is centralized transportation on the opposite side of the boundary wind lane 3 The beltway 4 and the centralized transportation beltway 4 are connected with the return air and filling pipeline lane 1 and the transportation and air intake lane 2 in the area. The area enclosed by the four roadways is the working face of the mining area where the coal mining operation is carried out. Through the centralized transportation belt 4, fresh air enters the area return air and fills the pipeline lane 1 and the area boundary air lane 3, and the exhaust air is transported from the area and the air inlet lane 2 to the main return air lane 5 for coal mining operations. The area has formed a normal prod...
