摘　　要：为确保采面生产安全,降低上隅角瓦斯集聚给煤岩回采影响,对2-607综采工作面上隅角瓦斯治理展开研究。由于开采的2^(#)煤为自燃煤层,将采空区埋管抽采口布置在散热带内,可避免埋管抽采增加遗煤自燃。现场应用后,上隅角瓦斯浓度控制在0.45%以内,采面日产量也由2000t提升至2800t,取得显著应用成果。In order to ensure the safety of the mining face and reduce the impact of gas accumulation in the upper corner on coal and rock recovery,the upper corner gas treatment technology of the 2-607 fully mechanized mining face is studied.Since the 2^(#)coal mined is a spontaneous combustion seam,it will The buried pipe extraction port in the goaf is arranged in the heat dissipation belt,which can prevent the buried pipe from increasing spontaneous combustion of coal.After field application,the gas concentration in the upper corner was controlled within 0.45%,and the daily output of the mining face was increased from 2000t to 2800t,and significant application results were achieved.
