Application of gob-side entry retaining technology in east two coal pillar working face of Saier No.6 Coal Mine

赛尔六矿在回收东二煤柱工作面期间,采用沿空留巷方式保留了回风上山巷,解决了下段回采的通风问题。设计了沿空留巷具体施工工艺流程,并在现场进行了应用,取得了较好的效果和效益。

During the recovery of the east two coal pillar working face in Tacheng No. 6 Coal Mine,the gob-side entry retaining method was adopted to retain the return air uphill roadway, and solved the ventilation problem of the lower mining section. The construction process of gob-side entry retaining was designed and applied in the field, and good results and benefits have been achieved.
