煤矿开采中巷道变形影响因素的分析
Analysis of Factors Affecting Roadway Deformation in Coal Mining
【摘要】 软岩巷道开采过程中,巷道的变形将不利于煤矿的安全开采,针对此情况,采用数值分析的形式对影响巷道变形的地应力及支护阻力的作用进行模拟分析,研究垂直应力、侧压系数及支护阻力对巷道变形的影响规律,从而为软岩巷道开采掘进过程中的支护系统设计提供参考,提高支护系统的稳定性,保证煤矿的开采安全。
【Abstract】 In the process of soft rock roadway mining, the roadway deformation is not conducive to the safe mining of coal mine. In view of this situation, the role of in-situ stress and support resistance affecting roadway deformation is simulated and analyzed in the form of numerical analysis, and the influence law of vertical stress, lateral pressure coefficient and support resistance on roadway deformation is studied, so as to provide reference for the design of support system in the process of soft rock roadway mining and excavation, improve the stability of support system and ensure the mining safety of coal mine.
【Key words】 soft rock roadway; deformation; vertical stress; side pressure coefficient; support resistance;
