Study and practice on technology of three-zones linkage 3D coalbed methane drainage in coal mining area
Abstract：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.
