高瓦斯综采工作面充填墙体沿空留巷研究

Study on Gob Side Entry Retaining of High Gassy Fully Mechanized Mining Face

为解决高瓦斯矿井沿空留巷巷旁支护技术难题,以贺西煤矿3302(2)综采工作面回风平巷为研究对象,根据地质工程条件,提出沿空留巷巷旁支护方案及快速充填墙体工艺,为煤矿的安全生产提供了有力保障。

In order to solve the technical problems of roadway support along gob-side entry retaining in high-gas mine, this paper takes the return airway of 3302（2） fully mechanized coal face in Hexi Coal Mine as the research object. According to the geological and engineering conditions of the coal mine, side support programs and rapid filling wall technology for the safe production of coal provides a powerful guarantee.
