煤矿钻孔抽采瓦斯技术研究

Study on gas drainage technology of coal mine

瓦斯灾害严重威胁煤矿安全,瓦斯抽采是防治瓦斯灾害最有效的措施,通过合理布置钻孔、选择有效的封孔方法,以达到钻孔最优的抽采效果。顺层交叉钻孔布置方式抽采瓦斯和采空区高位钻孔抽采瓦斯是有效解决采煤工作面瓦斯超限的重要措施,为煤矿的安全生产提供了保障。

Gas hazard seriously affects hazards,through the reasonable layout method,in order to achieve optimum drilling normal production,and gas drainage of gas drainage boreholes,and the drilling is an efective measure to prevent gas selection of effective boreholes sealing extraction effect.The gas drainage method of bedding crossing arrangement,and gas drainage method by using high position boreholes in goaf, are to prevent gas overlimit on coal mining face,which has ensured the safe production of coal two important measures mine.
