发布时间：2018-11-10 16:46
【摘要】：根据五虎山煤矿近距离煤层群开采的特点,在分析矿井瓦斯赋存和涌出规律、计算工作面瓦斯涌出量的基础上,提出了"定向长钻孔区域预抽、邻近层卸压抽采、采空区瓦斯抽采"的适合近距离高瓦斯煤层群开采的分源瓦斯治理技术。该技术的应用使得矿井瓦斯涌出得到有效治理,确保了采掘工作面的安全高效生产。
[Abstract]:According to the characteristics of short distance coal seam group mining in Wuhushan Coal Mine, on the basis of analyzing the law of gas occurrence and emission and calculating the amount of gas emission in the working face, the paper puts forward that "the region of directional long borehole is pre-pumped, the adjacent strata are discharged by pressure". Gas drainage in goaf is suitable for close distance and high gas coal seam mining. The application of this technology can effectively control the gas emission and ensure the safe and efficient production of the mining face.
