由煤炭科学研究总院重庆分院和乌鲁木齐矿务局六道湾煤矿共同研究的“放顶煤综采工作面空分机输送氮气防灭火技术”对急倾斜特厚煤层放顶煤综采工作面防灭火的氮气来源方式、防灭火工艺系统及污氮的利用进行了全面的研究、考察,并利用注氮灭火提前启封东二南放顶煤综采面,取得了良好的效果,为保证正常生产提供了可靠的技术。该项技术的研究成功,不仅可以减少自然发火频率,保障综采面的正常生产,提高工作面出煤量20%,
By the coal ministry of Chongqing Branch of Coal Research Institute and Urumqi coal mine Liu Daowan coal mine jointly study the “top coal caving mining face air separation unit to prevent fire fighting technology” on the steep-inclined extra-thick seam fully mechanized coal caving face Fire-resistant nitrogen sources, fire-fighting technology systems and the use of nitrogen pollution conducted a comprehensive study and study, and the use of nitrogen injection fire ahead of the East Second Caving Caving fully mechanized mining face, and achieved good results, in order to ensure normal Production provides reliable technology. The successful research of this technology can not only reduce the frequency of spontaneous combustion, ensure the normal production of fully mechanized coal mining face and increase the coal output by 20%
