| 摘 要： | 含瓦斯厚煤层开采后,矿山压力变化对采场瓦斯涌出规律有决定性作用。根据靖远煤业公司魏家地矿110综放面以及韩城局桑树坪矿3307综采面的矿压观测和瓦斯监测结果,得到了基于矿山压力变化的采场瓦斯涌出特征,并提出设置顶板瓦斯排放巷是周期来压时管理采场瓦斯的重要方法,为有效防治瓦斯事故以及合理抽取利用瓦斯资源提供了理论依据和技术支持。

| Abstract: | After mining in methane-rich thick seams, the law of gas emission of coal caving is determined by the change of underground pressure. Based on results of underground pressure watching and gas monitoring in 110 fully-mechanized top coal caving of Weijiadi coal mine, Jingyuan mining company and in 3307 comprehensive mechanized coal caving of Sangshuping coal mine, Hancheng ming bureau, the gas emission characteristics of coal caving on the basis of the change of underground pressure is obtained. The paper proposes that the gas drainage roadway is an important gas management method of caving coal as the periodic weighting. This research provides theoretical base and technical support for effectively preventing gas disaster and reasonable draining and using gas resource. |
