广西大新锰矿急倾斜矿体采空区处理

摘要

随着矿区开采深度的增加，地压也在不断增加，必须结合实际情况选择采空区处理方法。介绍常见空区处理方法，通过阐述广西大新锰矿目前的开采现状及空区现状，提出空区处理问题，结合广西大新锰矿开采现状、地质情况和采矿方法，选择封闭采空区做为目前空区处理方法，同时随着开采深度的增加，可考虑结合矿柱回收选用崩落法。%With increasing mining in depth,we think pressure is also increasing and goaf disposal methods must be selected.Common cavity treatment is by explaining in Daxin Mn mine mining situation and present situation of gap. Combined with the new status quo.We have found geology and mining manganese mining method in selecting close gob area as currently empty methods with increasing mining depth to consider combining selection in caving pillar recovery.
