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。
The coal seam in YaPing TaPing coalfield has not yet been exploited, with deep burial, large pressure and complex structure. The study on geomechanics and tectonic stress in deep rock mass is weak, and roadway support in mining must be difficult. In order to determine the reasonable roadway support plan, the stress of surrounding rock in deep mine is analyzed firstly, and the stress distribution characteristics of surrounding rock are obtained, which provides the basis for the design parameters of support. According to geological conditions, stress analysis and the design of the adjacent mine, design support program. The numerical simulation method is used to test the effect of roadway support design. It is concluded that this supporting scheme can effectively control the deformation of surrounding rock of horizontal roadway in special deep mine.
