摘　　要：为有效预防大佛寺煤矿小煤柱开采采空区遗煤自燃,采用理论分析、实验测试和现场测试的方法,以大佛寺煤矿40103工作面小煤柱开采为例,测试分析了工作面漏风通道。研究结果表明:40103工作面回采过程中,采空区内小煤柱破碎,与40104采空区之间存在通畅的漏风通道,最大漏风速率82 m/min。In order to effectively prevent spontaneous combustion of residual coal in the goaf of small coal pillar mining in Dafosi Coal Mine,theoretical analysis,experimental testing,and on-site testing methods were adopted.Taking the small coal pillar mining in the 40103 working face of Dafosi Coal Mine as an example,the air leakage channel of the working face was tested and analyzed.The research results show that during the backfilling process of the 40103 working face,small coal pillars in the goaf are broken,and there is a smooth air leakage channel between the goaf and the 40104 goaf,with a maximum air leakage rate of 82 m/min.
