摘要
针对井下二盘区大巷煤柱回采工作面邻近老空区,通过SF6示踪气体漏风通道检测技术查找煤层之间漏风通道,对存在漏风的密闭墙进行了封堵,实施均压技术优化了通风系统,进一步减少了采空区漏风,保证了煤柱工作面的安全回采。
According to the adjacent goaf of coal pillar working face in the second roadway panel,searched the air-leakage passage between two coal seam with SF6 air-leakage detection technique,sealed the air-leakage airtight wall,and further reduced the air-leakage goaf with pressure balancing to optimize the ventilation system.The safe mining of coal pillar working face was guaranteed.
