大红山铜铁矿床地面塌陷规律及其预防

Law of Ground Collapse Law of Dahongshan Copper-iron Deposit and Its Prevention

针对大红山铜铁矿床开采中矿体顶板突水以及地面塌陷的问题 ,开展了矿区水文地质条件、岩溶发育特征及突水后塌陷分布规律的研究 ,探讨了塌陷产生的原因、规律 ,提出了避免“强疏强排”、帷幕注浆、带压开采等综合治理措施。

In light of the problems of water irruption of orebody ceiling and ground collapse in the mining of Dahongshan Copper-iron deposit, the hydrogeological conditions, characteristics of karst development and after-water irruption collapse distribution law in the mining area are studied and the causes for the collapse discussed. The comprehensive measures are proposed, including avoiding forced drainage, curtain grouting and pressure mining.
