摘要
为解决耿村煤矿13190工作面瓦斯涌出量日益增加的问题,运用采动裂隙椭抛带理论,对覆岩采动裂隙演化规律及高抽巷抽采瓦斯机理进行了分析,得出该矿13190工作面高抽巷合理布置层位。实践表明,该方法解决了13190工作面、上隅角、回风巷瓦斯浓度大的问题,并将其控制在0.8%以下,保证了13190工作面的安全高效生产。
To solve the problem of gas emission increasing on 13190 working face in Gengcun Coal Mine, By the theory of elliptic parab- oloid zone,the law of overburden fissures and the gas extraction mechanism of high drainage roadway were analyzed in the paper,the reasonable horizon of high drainage roadway was obtained on 13190 working face in Gengcun Coal Mine,and the obtained results were applied into practice. The application of the above measures has solved the problem of high gas concentration of 13190 working face, the upper corner and the return airway,the gas concentration is controlled within 0.8% ,and has ensured safe and high-efficient production of 13190 working face.
