摘要
阳谷茌平煤田煤层尚未开采,埋藏深、地压大、构造较复杂,且深部岩体地质力学与构造应力研究方面较薄弱,开采中巷道支护必定困难。为确定合理的大巷支护方案,首先对深部矿井围岩应力做出分析,得出围岩应力分布特征,为支护设计参数确定提供依据。根据地质条件、应力分析和邻近矿井设计方案,设计出支护方案。运用数值模拟方法对巷道支护设计的效果进行检验。得出该支护方案能够有效地控制特深矿井水平大巷围岩的变形。
Yanggu Chiping untapped coal seam buried deep ground pressure large structures are complex and deep rock mass geomechanical and tectonic stress research is weak, mining roadway support must be difficult. To determine a reasonable roadway support programs, first make a deep mine surrounding rock stress analysis,the surrounding rock stress distribution,provide the basis for supporting design parameters determined; according to the geological conditions,stress analysis and design of adjacent mines, design support program： numerical simulation of roadway supporting design effects for testing. The results support scheme for supporting the program can effectively control the deformation very deep level mine roadway surrounding rock.
