摘要
为解决单一煤层瓦斯抽采技术难题,针对晋城矿区实际,基于瓦斯抽采、煤炭开采时空接替关系,通过理论研究和工程实践,提出了适合高瓦斯矿区特点的三区联动立体抽采模式,形成了高瓦斯矿区瓦斯抽采技术体系,显著提高了高瓦斯矿区瓦斯抽采水平和矿井安全效益。
In order to solve the technical problems of the gas extraction in coal mines with high gash coal seam,according to the actual conditions in Jincheng mining area and with the theoretical research and project practices,put forward the model of three-zones linkage 3D gas drainage in coal mining area based on time and space sequence of gas extraction and coal mining.A set of a rapid and high efficient gas extraction technical system suitable for Jincheng mining area was formed.The application of those technologies could obviously improve the efficiency of gas drainage and safety benefits of the mining area.
