忻州窑矿综采工作面骑大巷开采技术探讨

Probe into the Mining Technology of Riding on Large Roadway Adopted in the Fully Mechanized Coalface of Xinzhou Coal Mines

大同煤矿集团公司忻州窑矿在开采大巷上方的煤柱时为了更多地回收煤炭资源,减轻开采后残留煤柱对大巷的影响,采用了综采工作面骑在大巷上方开采的方法,使大巷在开采过后处在采空区的压力降低区内,取得了较好的效果。

In order to recover more coal resources,and reduce the influence of residual pillars after mining on the large roadway,Xinzhou coal mines of Datong Coalmines Group Co.adopt the mining method of making the fully mechanized coalface ride on the top of large roadway in the case of mining the pillars above the large roadway,making the large roadway locate in pressure reduction zone of the worked out section after mining,and obtaining better results.
