摘要
Abstract
Gas of short distance adjacent coal seams under influence of coal seam mining would flow to the working face through circulating tunnels developed from mined fractures,it leads to gas transfinite.Characteristics of gas in short distance adjacent coal seams and technology of gas extraction by high -located drainage roadway were studied in this paper.The results were successfully applied into engineering practice and have good effects.关键词
