沿空留巷矿压显现规律模拟研究

Simulation research on the law of strata behavior in gob-side entry retained

结合冀中能源股份公司葛泉矿1528工作面运输巷的工程条件,在关键层理论研究成果基础上,通过计算机数值模拟的方法,建立了反映岩层基本特征的力学模型,研究了留巷上方顶板断裂的应力特征、变形特征和破坏特征。

Taking the engineering conditions of haulage roadway of No.1528 face in Gequan Coal Mine of Jizhong Energy Group Co.,Ltd.into consideration and based on the research findings of Key Stratum Theory,the paper has established a mechanical model which could reflect the basic features of rock stratum by the method of computer numerical simulation,and researched the characteristics of stress,deformation and damage of fractures on the roof beyond the gob-side entry retained.
