摘要
金召矿床矿体-150m以上部分开采7年多以来形成的采空区面积达4万m2,对周围居民生命财产及厂矿安全生产构成极大威胁。较详细介绍了全尾砂胶结充填技术在金召铁矿采空区治理中发挥的作用,治理效果显著,基本消除了矿区采空塌陷地质灾害隐患,为小型矿山采空区治理工作提供技术指导。
In the past 7 years, the mined out space is no less than 40000 square meters in the northern Jinzhao Orebody above the -150 meter, which is a great threaten to the life and property of the people or the safety produc- tion of mining business around. The important function of the tailing cemented filling technology in the course of the mined out space treatment of the Jinzhao Iron Mine is specified in detail, and the treatment effect is very good. The potential geological disaster danger from the mined out space is basically eliminated. It can provide some technical instructions to the mined out space treatment work of small mines.
