In order to improve the ability of fire prevention and control in Wangjialing Coal Mine and ensure the safety of coal production,the factors of spontaneous combustion during coal mining were analyzed in combination with the occurrence of 4#coal seam and the characteristics of spontaneous combustion,etc.,and based on the concept of"prevention first and comprehensive treatment",the technical solutions of nitrogen injection,grouting and air leakage prevention were determined.Taking 18105 coal face of 4#coal seam as an engineering example,the technical measures for fire prevention and control were analyzed in detail.The research results can provide experience for other mine fire prevention and control schemes.
