摘要
阳煤集团三矿通过研究采用邻近层抽采钻孔、伪斜高抽巷抽放、控制割煤速度、斜采等技术措施,使15~#煤层K8201综放工作面初采期间,采空区顶煤垮落不稳定的涌出瓦斯得到了有效的排放,保证了初采期间的通风瓦斯管理安全。
Yangquan NO.Three coal mine,by studied the adjacent layers of boreholes,pseudo-inclined High pumpingLane drainage,control of coal cutting speed,slope mining and other technical measures to effectively control the gasemissions during15#fully mechanized top coal caving face guaranteed the safety ventilation and gas managementduring the initial mining
