摘要
某煤矿煤层瓦斯压力与含量相对较高,使得矿井井筒揭煤过程中存在很大的困难。经应用诸多技术手段,例如超前钻孔等方法,同时通过远距离爆破揭煤的技术手段,将揭煤时的突出危险消除,为煤矿矿井井筒施工安全进行提供了保障。
The coal seam gas pressure and content is relatively high, so that the coal mine shaft uncovering coal is very difficult. Through the application of many techniques, such as advanced drilling and other methods, and through the long-distance blasting technology, the outburst danger of coal mining is eliminated, which provides a guarantee for the safety of mine shaft construction.
