| 摘 要： | 城郊煤矿为瓦斯矿井，但2703工作面属于瓦斯异常区域。在工作面回采期间，瓦斯涌出量不断增加，工作面瓦斯易超限，严重制约了工作面的正常回采工作。为了达到降低工作面瓦斯浓度，解决工作面瓦斯超限，实现工作面的安全、高效回采工作，采取了高位裂隙瓦斯抽放钻孔对煤岩层卸压带瓦斯进行抽放，取得了良好的效果。

| Abstract: | The Chengjiao mine is a lower gassy mine,but 2703 face belongs to the gas uneven area.During the mining process, the gas emission quantity continues to increase, and the gas concentration in working face is overrun, which seriously restricts the normol mining work. In order to reduce the gas concentration, solve the problem of gas overrun and achieve the safe and efficient work in working face, the method of high fracture drainage technology was applied to draw out gas, which made a good effect. |
