摘要:
为了合理布置地面抽采瓦斯钻孔，基于矿山压力与顶板控制理、保护层开采理论等，研究了地面钻孔平面布置和结构，地面钻孔抽采瓦斯量和抽采瓦斯浓度随工作面距钻孔距离的变化规律，同时利用双示踪技术对地面钻孔抽采范围进行了测试，综合考察了地面钻孔抽采煤层卸压瓦斯的有效范围。结果表明：地面钻孔抽采瓦斯有效范围不小于200m。
Abstract:
In order to rationally arrange the ground drillings of gas drainage, based on the theory of ground pressure and strata controlling and the mining of protective layer, the layout and structure of the ground drillings, the relation of gas drainage volume and gas extraction concentration of surface drillings and the distance of ground drillings and workingface were studied, while dualtracer technique was applied to test the range of gas extraction of surface boreholes, the effective range of coal seam relief pressure gas of the ground drilling was surveyed . The results showed that effective range of gas extraction of surface boreholes is not less than 200m.
