摘要
概述了莱芜矿业有限公司各矿床的水文地质条件、采矿方法沿革,针对矿体不稳固且水大的特点,研发了预控顶上向分段胶结充填采矿法。对该采矿方法采场布置形式、预控顶的施工工艺、落矿方式及有关参数进行了介绍,对适应条件及使用效果进行了评价。
Hydrogeological conditions and the evolution of mining methods of various deposits in Laiwu Mining Co. , Ltd are summarized. Aimed at the characteristics of ore body being unsteady and floodwater, the top pre-control substoping-cementation method was developed. The techniques of top pre-control, manners of ore falling stope arrangement form for this mining method, construction as well as some related parameters are introduced, with their compatible conditions and effect of use evaluated.
