浅式骨架孔在难控制顶板掘进中的应用

Shallow Pattern Skeleton Hole in Unmanageable Roof Excavation

虽然科学技术不断得到发展,但顶板事故仍然在煤矿事故中占有很大比重,尤其目前淮北矿区随着采深的加大、恶劣采场的开采,掘进巷道顶板控制已成为安全生产的瓶颈问题。本文将突出煤层揭煤时施工骨架孔的方法引入到掘进顶板管理中,通过实践应用取得了较好效果,为矿井安全高效发展开辟了一个有效途径。

Although science and technology have continued to develop, but roof accident occupies an important place in coal mine, espe- cially the current mining depth was increased in Huaibei mining area and its poor stope was mining, roof control roadway safety has be- come a bottleneck problem. This article includes that method of construction skeleton hole can be brought in management of roof excava- tion during outburst coal seam lift up coal,it achieved good results through the practical application, and it has opened up an effective and efficient way for the development of mine safety.
