凡口矿的地压活动分析及防治建议

GROUND PRESSURE OF THE FANKOU Pb-Zn MINE AND THE COUNTERMEASURES OF PREVENTION AND CURE

凡口铅锌矿深部开拓后 ,部分工程发生变形、垮塌 ,给生产和安全带来威胁。认为矿区地压活动是与矿区构造、岩石力学性质、水文条件、开采深度等密切相关的 ;并建议选择合理的工程设计、施工方案、支护措施 。

With the development of deep exploration in the Fan Kou lead-zinc mine, some engineering begin to distort or collapse. It will damage the safe production. The analyses shows that the actions of ground pressure are determined by structure, mechanical property of rocks, water condition, and exploited depth. It has been suggested to choose logical project design, construction scheme, and support measure to reduce ground pressure damage.
