摘要
针对忻州窑矿巷道存在的应力集中及矿压显现严重现象。通过二氧化碳致裂技术替代炸药爆破对14-3#层8308工作面5308巷的致裂切顶,改善了原爆破切顶安全性差、可控性低、环境恶劣的状态,切顶卸压效果显著,为相近条件下的矿井切顶卸压工作提供了参考依据。
For the stress concentration and mine pressure in the roadway of Xinzhouyao Mine are serious, by replacing the explosive blasting with the carbon dioxide cracking technology on the cracking and cutting top roof of the 5308 lane in the 14-3# 8308 working face, the status of the poor safety of the original blasting cutting top roof, the low controllability, the bad environment are improved, and the effect of the top roof cutting and pressure relief is remarkable It provides a reference for the work of the mine top roof cutting and pressure relief under the similar conditions.
