煤矿开采中地应力测量技术的应用实践分析

Application and Practice Analysis of Ground Stress Measurement Technology in Coal Mining

基于地应力对围岩变形及破坏的影响,分析地应力测量技术在煤矿开采中的应用。具体研究中采用FALC3D软件,从垂直地应力、水平地应力和最大主地应力角度分析地应力对围岩变形及破坏的影响。另外,分别介绍地应力测量技术在常规煤矿开采和深部煤矿开采中的应用,确认地应力测量技术的具体应用价值。

Based on the influence of in-situ stress on the deformation and failure of surrounding rock,the application of in-situ stress measurement technology in coal mining is analyzed.In the specific research,the FALC3D software was used to analyze the impact of geostress on the deformation and failure of surrounding rock from the perspectives of vertical geostress,horizontal geostress,and maximum principal geostress.In addition,the application of geostress measurement technology in conventional coal mining and deep coal mining was introduced separately to confirm the specific application value of geostress measurement technology.
