下行通风在综采工作面优化设计中的应用

Application of Downward Ventilation in the Optimization Design of Fully Mechanized Mining Face

针对中煤新集口孜东矿中央区通风系统不独立、通风能力不足、采区(工作面)接替紧张和煤层自然发火隐患问题,通过采用下行通风优化工作面设计,解决了安全隐患并取得了良好的效果,值得类似矿井借鉴。

Aiming at the problems of ventilation system independence, insufficient ventilation capacity, tense replacement of mining area (working face) and hidden danger of spontaneous combustion of coal seam in the central area of Kouzidong Coal Mine, China Coal Xinji Co., Ltd., the hidden danger of safety was solved by optimizing the design of working face with downward ventilation, and good results were obtained. It is worth learning for similar mines.
