针对乌东煤矿急倾斜特厚煤层复杂条件,采用数值模拟、现场开采试验和监测等方法,开展了急倾斜特厚煤层瓦斯共采可行性研究。通过上层开采卸压下层煤层,便于下层通过巷道抽采瓦斯,分析了上层开采对下层煤层的应力和瓦斯等气体运移规律的影响,设计了现场瓦斯治理技术方案和管理措施,同时进行了效果分析。
According to the complicated conditions of the steeply-inclined and extremely thick coal seam in Wudong Coal Mine, the feasibility of gas co-mining in the steep-inclined and extra-thick coal seam was studied by means of numerical simulation, field mining test and monitoring. Through the upper mining pressure relief of the lower seam, so that the lower gas drainage through the roadway, analysis of the upper seam on the lower seam stress and gas and other gas migration rules, the design of the site gas control technology programs and management measures, while the effect analysis.
