摘要
介绍了目前国内规模最大的地下充填开采矿山,该矿山隶属五矿邯邢矿业有限公司,矿区位于安徽省霍邱县,矿山由两个矿床组成,矿石主要为镜铁矿、磁铁矿,矿体特点是走向长、延伸深、厚度大、倾角陡。根据矿床赋存条件,阐述了矿山开拓系统的选择、规模化开采的采矿方法、特大型采场结构参数及特点、开采顺序的选择、系列大型采掘设备配备、大流量充填系统的构建思考及建设、充填料桨连续与间断制备系统的选择、采场的开采、充填作业以及充填体强度的控制。该矿山将于"十二五"末完成示范矿山建设,为特大型以及未来的超大型地下矿山的提供可借鉴的经验,逐步形成我国特大型地下矿山规模化开采关键技术。
The largest scale underground mine with filling mining method at present in China is introduced. This mine is under Minmetals Hanxing Mining Co. Ltd. and it is located in Huoqiu County, Anhui Province. There are two ore deposits of magnetite and specularite in the mine. The ore-body is characterized with long strike, wide extension,large thickness and high inclination. According to the occurrence of the ore deposit, such issues are described as the choice of the development system, the mining method for large scale stoping,the structural parameters and characters of extra-large stope, the selection of mining sequence, the option of extra large mining equipments, the deliberation and construction of large scale filling systems, the choice of continuous and intermittent preparation system for filling pulps, and the control of the mining, the filling, and the strength of the filling body. The mine will be completed at the end of 12th Five-year Plan of China to be a model project. It provides expe- riences for extra large and super large underground mining for the future and forms the key technique for extra-large under- ground mine in China~
