摘要
根据水峪矿放顶煤综采工作面上、下顺槽的变形、破坏进行围岩松动探测 ,理论分析和参数确定。通过实践检验 ,技术上可行 ,经济上合理 ,效果明显 ,已广泛地进行了推广应用。
The combined supporting techniqe was tested in the headentry and tailentry of sublevel caving face in Suiyu mine.The broken of surrounding rock was monitored,correspounding parameters were analysed,which showed this technique was feasible and reasonable.
