On the Goaf Treatment and Sublevel Caving Proposal in the 1158 m Section of Rongguan Multi-metal Mine

针对内蒙古兴业集团融冠矿业多金属矿西采区1 158中段产生的大小不同的采空区以及后期采矿方法的过渡问题,对矿区地质特征、采空区和露天工程情况、放顶方案、爆破技术参数和施工方案进行了深入的分析,制定出合理的方案,使处理采空区和后期使用无底柱分段崩落法回采形成覆盖层得以实现。

In view of various goafs in the 1 158 m middle section of the west mining area of Rongguan multi-metal mine of Xingye Group,Inner Mongolia,and the mining transferring later,the geological features,the circumstances of goafs and surface project,sublevel caving program,blasting technique parameters and the construction program are deeply analyzed and a reasonable proposal is given in detail to create favorable conditions for dealing with the goafs and forming the cover for the non-pillar sublevel caving in the following sections.
