Abstract: Take Songhe Coal Mine as an example, aiming at the short distance coal seams in coal mines that suffer the problems of gas outburst, this paper raises the method of mining the upper and lower protective seam and drilling hole to extract gas, broadening the space of releasing gas concentration and pressure, effectively release gas in nearby seams, and achieve very good results. This research achievement plays a very good referential role to design schemes and production management.

Key words: coal and gas outburst, short distance coal seams, gas control, protective seam
