【摘要】 根据地质构造因素控制煤层顶板稳定性作用的研究,提出煤层顶板稳定性预测评价的矿井地质构造特征解析方法.选择平顶山十三矿为典型研究区,通过对矿井地质构造几何特征综合研究,即矿井地质构造特征、矿井构造应力场、顶板岩体结构力学特征3个因素的综合研究,对煤层顶板稳定性进行了预测.工程实践证明,地质构造解析法可以对煤层顶板稳定性进行准确预测.更多还原

【Abstract】 Based on the research result of control action of structure to the stability of roof, the author puts out tectonic synthesis method for predicting the stability of roof. Takes colliery No13 of Pingdingshan coal mines as the sample, through the comprehemsive research on the geometry features of structure, which include structure features, tectonic stress field and mechanics feature of roof, and proceeds the stability prediction of roof. The engineering practice shows that the stability of the roof can be predicted accurately by tectonic synthesis method.更多还原
