摘要
基于芦岭煤矿的地质条件,采用数值计算、三维封闭式物理模拟等方法和手段,对综放工作面覆岩破裂与移动规律,以及裂隙瓦斯运移规律进行了综合研究,分析了高位裂隙瓦斯运移特征,确定了瓦斯运移的关键层位,找出适合煤与瓦斯共采的基本条件,初步形成综放工作面瓦斯综合开采技术,并将其应用于工程实践。
In this paper,the present study situation on the co-extraction of coal and gas both at home and abroad was described,comprehensive study was made on the failure and movement law of cover rock and the migration law of fracture gas by means of numerical computation and 3-d closed physical simulation according to the geologic conditions of Luling Mine,the migration characteristics of the highly-located fracture gas was analyzed,the key layer where the gas migrates was fixed,the basical conditions suitable for the co-extraction of coal and gas were found out,and a comprehensive gas extraction technology for the fully mechanized caving face was preliminarily formed and has been successfully applied in the engineering practice.
