摘要
竹峪金矿区控矿构造经多期复合作用,裂隙发育,矿体顶底板围岩破碎,矿块回采中经常发生顶板冒落、坍塌,堵塞回采通道,无法正常退采,造成较大的资源浪费。针对以上问题,对竹峪金矿区采矿技术进行了改进,采用小木架支护法,在冒落采区中开辟回采通道,回采矿石。实践证明,小木架支护法解决了竹峪金矿区复杂矿体回采的技术难题,产生了较好的经济效益,也为我国同类矿山提供了可供借鉴的方法和经验。
There exists fracture development in ore-controlling structure of Zhuyu gold mine areas after multi-phase composite action, with wall-rock on the roof and floor crushed, resulting in roof frequent caving or collapse during stoping, mining passage blocked, huge resources lost. In view of above problems, the mining technology has been improved in Zhuyu mine areas by supporting with small wooden stand and opening stoping passage in the caving mining area. It is proved that the supporting method with small wooden stand can resolve the existing problem in a cost-effective way. Such method and practical experience can also be taken as reference for other mine with similar problem.
