近距离多煤层开采取消均压系统可行性研究

Feasibility Study on Banning Pressure Equalizing System in Short-distance Multi-seam Mining

均压通风存在通风设施数量多、工作面温度高、作业环境差、均压风机管理困难等缺点,尤其是近距离多煤层开采的矿井各均压工作面间风压容易相互作用,影响矿井安全生产。通过研究山西某矿相邻的81022和81024工作面采取不同措施时的治理效果,确定防止邻近采空区气体大量涌入本工作面的可靠手段,实现取消均压通风系统的目的。

Aiming at the disadvantages of large number of ventilation facilities,high temperature of working face,poor working environment,difficult management of pressure equalizing fan in pressure equalizing ventilation system,and the interaction of pressure equalizing working faces in short-distance multi-seam mining,the author probes into the control effect of different measures taken in the adjacent 81022 and 81024 working faces of a certain colliery in Shanxi Province,determining the reliable means of preventing the gas from the adjacent goaf into the working face to achieve the purpose of banning the pressure equalizing ventilation system.
