| 摘 要： | 为解决瓦斯矿井综放面推采过高瓦斯区域时,上隅角瓦斯易超限的问题,结合赵庄二号井2309工作面地质情况,研究实施了工作面采空区瓦斯抽采和上隅角软管抽放的综合治理技术。实践表明:在2309综放工作面回采期间,上隅角瓦斯浓度得到有效控制,平均为0.15%,最高为0.36%,为工作面安全生产提供了有力保障。

| Abstract: | In order to solve the problem that the gas in the upper corner is easy to exceed the limit when the gas area is pushed too high in the fully mechanized caving face of the gas mine,combined with the geological situation of the 2309 working face of Zhaozhuang No.2 shaft.The practice shows that the gas concentration in the upper corner of 2309 fully mechanized top coal caving face is effectively controlled,with an average of 0.15%and a maximum of 0.36%,which provides a strong guarantee for the safe production of the working face. |
