根据窑街金河一号井16211工作面切眼改造过程中火灾的特点及其发展状况,采用黄土复合胶体灭火技术和一次成孔注胶防灭火钻具,直接处理着火点和高温点,成功地熄灭了大面积高温区,建立了胶体隔离带,有效地阻止了火区向采空区深部发展,从根本上解决了自燃引起的危害。黄泥复合胶体防灭火技术工艺简单,对西部缺水地区煤层自燃火灾有推广意义。
According to the characteristics and development of the fire in the process of cutting and reconstructing 16211 working face of Jinhe No. 1 Well in Yiwu Street, the fire and high temperature points were directly treated with the composite colloidal fire extinguishing technology of loess and one hole injection plastic fire-extinguishing drill, Extinguished a large area of high temperature, the establishment of a colloidal isolation zone, effectively preventing the fire zone to the deep development of goaf, a fundamental solution to the hazards caused by spontaneous combustion. The technology of anti-fire of yellow mud composite colloid is simple and has the promotion significance to the spontaneous combustion of coal seam in the water-scarce area of western China.
