Embodiment Construction
[0020] Such as image 3 As shown, a safe and clean ventilation system suitable for the mining face of the 110 method of roof cutting and pressure relief, including the return air downhill roadway 6 in the mining area and the belt downhill roadway 4 in the mining area, which are located in the center of the mining area and run through the entire mining area. The return air downhill roadway 6 is located on the left side of the tape downhill roadway 4 in the mining area, and the right side of the tape downhill roadway 4 in the mining area is the right wing recovery working face. The track downhill roadway 5 is also used as the right boundary air inlet lane, and the left side of the return air downhill roadway 6 in the mining area is the left wing recovery working face. There is a left boundary track downhill roadway 16 that runs through the entire mining area at the left boundary of the mining area. The roadway 16 is also used as the air inlet lane on the left boundary. The mine ...
