| 摘 要： | 富力煤矿在-310中18-2#层遇到断层后,工作面月推进度7~10 m,采空区长期处于氧化带。该矿通过利用DM系列注氮系统,消除了综放工作面采空区自燃发火隐患,保证了工作面正常回采,取得了良好的经济效益。

| Abstract: | After the faults were met in 18-2# coal seam,-310 m level in Fuli Coal Mine,the face went forward on the speed of 7 to 10 meters in a month,the goaf was in a long-time oxidation zone.By application of DM series nitrogen injection system,the fire danger is removed in the goaf of fully mechanized face with caving of roof coal.The normal face mining is ensured.The good economic benefit is obtained. |
