深井巷道变形破坏形式与安全支护技术研究的探讨

冬瓜山铜矿是典型的千米深井矿山，深井具有高应力、存在岩爆倾向的特点。根据采切工程的性质、岩石物理力学试验、服务时间及矿岩的破碎程度，总结了冬瓜山矿井巷道工程变形破坏的一般规律。对影响冬瓜山深井巷道变形破坏形式的主要影响因素从地质构造条件、技术及管理等方面进行了深入的分析，对凿岩硐室、隔离矿柱、出矿巷道、出矿进路等主要回采作业地点中已出现的变形破坏情况，采用了不同的锚杆、喷锚、喷锚网＋锚索联合支护形式及参数支护措施，取得了很好的效果，基本保持了采切巷道工程的稳定性，为下步安全回采作业及大量出矿创造了很好的条件。

DISCUSS ABOUT LANEWAY DISTORTION OF DESTROY STYLE IN DEEP WELL AND SECURITY SUPPORTING TECHNIQUE RESEARCH

Dongguashan Copper Mine is a kilometer deep mine, which has such characteristics as high stress and rockburst possibility. On the basis of character of mining, physical and mechanical tests of rock, serving hours and crashing degree of rock, it summarizes common rules of laneway project of Dongguashan Copper Mine. This paper analyzes mostly influencing factors of laneway distortion and destroys from the aspects of terra structure and technique and management. It also introduces diverse anchor poles, sprayin...
