煤矿综放工作面沿空巷道大多属于采动软岩巷道 ,巷道变形破坏剧烈且维护十分困难。本文在现场调研基础上 ,根据新集煤矿综放开采的实际生产地质条件提出了对综放巷道实施卸压工程的总体技术方案。通过计算机数值模拟方法 ,设计并确定了有效控制沿空风巷大变形的卸压工程方案的具体技术参数。实践证明 ,设计的方案与参数合理可行 ,取得了显著的技术经济效益
Most of the gob-side entryways in the fully mechanized caving mining face of coal mines are mostly mining soft rock tunnels, and the deformation of the tunnels is violent and the maintenance is very difficult. Based on the field investigation, this paper puts forward the overall technical scheme of pressure relief project for fully mechanized coal mining roadway based on the actual production and geological conditions of fully mechanized caving mining in Xinji Coal Mine. Through the computer numerical simulation method, the specific technical parameters of the pressure relief engineering scheme for effectively controlling the large deformation of the wind lanes are designed and determined. Practice has proved that the design of the program and parameters reasonable and feasible, and achieved significant technical and economic benefits
