摘要
分析近年中国的能源消费结构,研究建立了不规则边角煤采场的围岩结构力学模型,通过分析工作面老顶断裂位置与采场矿压规律的影响关系,为边角煤开采巷道布置与支护参数选择提供了理论依据。
This paper analyzed China＇s energy consumption structure in recent years,established the structural mechanics model of surrounding rock of irregular corner-coal pit and analyzed the relationship between the fracture position of the old roof and strata behavior regularity at the working face,providing a theoretical basis for roadway layout and support parameter selection for corner coal mining.
