摘要
柳湾煤矿61115综放工作面需要通过已经报废的小窑井筒区域,在钻探验证后,施工双层人工假顶,用充填法加固底板,形成良好的回采条件,保证了综采工作面顺利通过报废井筒区域。
The 61115 fully mechanized caving face of Liuwan Coal Mine needs to pass through the abandoned small kiln wellbore area.After drilling verification,the double layer artificial false roof is constructed,and the bottom plate is strengthened by filling method to form a good mining condition,which ensures the smooth passage of the fully mechanized mining face through the abandoned wellbore area.
