相邻工作面开采地表变形量研究

Study on surface deformation of adjacent working face mining

为确定13-0211工作面和14-0301工作面开采后的地表变形情况,采用《井工开采地表沉陷计算系统》软件,分别对单采13-0211工作面和单采14-0301工作面后的地表变形情况,及两个工作面采后的地表变形情况进行计算分析,计算的结果显示,相邻两个工作面开采后的地表变形值小于两个工作面分别单采后的变形值的累加和,说明两个工作面开采后的地表变形过程存在着抵消过程。

In order to determine surface deformation after mining in 13-0211 and 14-0301 working face,《 calculation system of underground mining subsidence 》software was adopted to calculate and analyze surface deformation after single mining 13-0211 and 14-0301 working face respectively and both mining these two working faces. The results showed that surface deformation after mining both adjacent working faces was less than accumulated sum of deformation after mining these two working faces respectively, which showed that countervailing processes existed in surface deformation after mining two working faces.
