超化煤矿是一座原设计能力90万t/a的矿井,矿井主井提升、通风、排水等环节经过技术改造后能力均已达到240万t/a以上。而超化矿副井操车系统提升能力仍为原设计90万t/a矿井配套的运输能力,副井提升能力的不足,严重制
Chaohua Coal Mine is a mine with a designed capacity of 900,000 t / a. The main shaft of the mine has been upgraded, ventilated and drained so that the capacity has reached 2.4 million t / a after technological transformation. The supercapacitor auxiliary shaft operation system to enhance the capacity of the original design is still 900,000 t / a mine supporting transport capacity, lack of auxiliary shaft to enhance capacity, serious system
