摘要
系统地开展了煤层顶板上覆岩石破碎厚度的控制因素定性和定量分析计算,通过列举影响煤层顶板上覆岩石破碎厚度的8项控制因素,借助灰色关联分析法,得出各控制因素的影响级别,得出主控因素为顶板岩石性质,其他控制因素影响程度由高到低依次为开采层厚度、回采方法、工作面长度、工作面推进速度、煤层倾角。研究结果可为矿井顶板控制以及矿井瓦斯治理提供有益参考。
The qualitative and quantitative analysis of the control factors of the crushing thickness of the overburden rock on the roof of the coal seam was carried out. By controlling the eight control factors that affect the crushing thickness of the rock mass in the roof of the coal seam,the influence level of each control factor was obtained by means of gray relational analysis method,and the main controlling factors are the rock properties of the roof. According to the influencing degree,other control factors are sorted,the mining layer thickness,mining methods,the face length,the speed of working face advancing,and the inclined angle. The results provide the necessary reference for mine roof control and mine gas control.
