摘要
Abstract
The omissive coal in the gob of thick coal seam with gangue fully mechanized caving mining working face shows a banding distribution in the space height , the thickness of the omissive coal in bottom is relatively uniform, the mixed zone of coal and gangue which contains the upper part of the omissive coal zone, its thickness is larger than the lower lfoating coal belt, which is the prevention and treatment focus of spontaneous combustion of residual coal in goaf. Combined Liangbaosi coal mine site conditions of 3404 working face, by the adoption of high drilling technology of ifre prevention, the leakage control technology plugging in two corners of the upper, injection carbon dioxide into gob, three-phase foam fire extinguishing technology, which ensure the safety mining in the section containing gangue of the 3404 working face.关键词
