地下残留空区处理技术及应用

Processing Technology of the Underground Residual Mined-out Area and its Application

空区处理是近年来矿山安全隐患治理的重点。由于空场采矿法具有开拓工艺简单,使用装备简便,是中小型矿山使用比较普遍的一种开采方法,但所残留的空区是矿山安全的重大隐患。针对不同空区存在环境,在不影响矿山正常生产的条件下安全、有效地进行处理,并能有效地将空区内残留的矿石进行回收,将为矿山带来巨大的安全和生产效益。利用分步作业,依次补顶的治理技术,成功地解决了困扰矿山的安全问题。

The treatment of residual mined-out areas is a focal point of mine security management in recent years.Since open pit mining method is a simple process with simple equipment,it is a common method for small and medium sized mines.But the residual mining-out area is the major risk in mine safety.For different environment in different mined-out area,how to safely and efficiently handle and recover the residual ores without disturbing the normal production will bring huge mine safety and production efficiency.In this paper, the technology of recovering the top in turn and operation step by step is a successful solution of the security issues that troubled mine.
