Abstract
To control the spontaneous combustion in the top-caving area of 1260 transportation lane of Yushe Coal Mine, based on the analysis of causes of spontaneous combustion of coal seams in the top-caving area, the guniting technology is used to prevent air from infiltrating into the interior of the top-caving area, the technology of water injection in the top-caving area and water injectionin the high temperature coal is used to control the spread of fire, the grouting technology is used to cover the high temperature coal body, and reduce the concentration of self-igniting signage gases such as CO to below 8×10-6 and maintain stability. Practice has proved that the comprehensive fire extinguishing technology using guniting, water injection and grouting can effectively deal with the problem of spontaneous combustion of coal in roadway top-caving area and provide safety for coal mine.关键词
