摘　　要：工作面回采后顶板垮落,地面出现裂隙,使采空区形成了漏风通道,残留浮煤自燃产生大量CO。采用进风巷安设风门,局部通风机给工作面供风,回风巷安设调节风门加阻调节工作面风压,使采空区漏风量减小,涌入工作面的CO浓度下降到24×10-6以下。采用该方法取得了良好效果。The roof collapses,and fissures appear on the ground after the coal wining of working face,so the passages of air leakage in gob are formed,large amounts of carbon monoxide are produced due to the spontaneous combustion of residual floats. A series of measures were carried out to adjust the air pressure on working face,including installing the air door in intake airflow roadway,using local fan for the air supply on working face,installing adjustable air door in return airway to increase wind resistance. Practices show that,air leakage quanlity decreased in mining goaf,the concentration of the carbon monoxide has reduced to 24 × 10- 6. The application of this method has achieved good effects.
