摘要
通过对特厚煤层撤退工作面自然发火原因分析,采用的目标注氮注水、科学合理利用通风系统,构建全面的气体监测体系,以及深度治理火区等综合治理措施,成功扑灭了特厚煤层撤退工作面自燃发火。
Based on the analysis of the causes of spontaneous combustion in the retreating working face of extra thick coal seam,the comprehensive control measures,such as target nitrogen injection and water injection,scientific and reasonable utilization of ventilation system,construction of comprehensive gas monitoring system,and in-depth control of fire area,have successfully put out the spontaneous combustion in the retreating working face of extra thick coal seam.
