摘要
Abstract
The CO concentration of the 8101 fully mechanized caving face is too high during the moving period,which may lead to the risk of coal spontaneous combustion in the goaf.According to the air leakage situation and geological condition of the working face,the reasons for CO overrun are analyzed.Some technical measures are adopted,such as the prediction and forecast technology of spontaneous combustion in the goaf,the nitrogen injection inerting technology in the goaf,the sealing of the upper and lower ends of the working face,the spraying of inhibitor,gel,the use of reverse return air pressure equalizing ventilation mode in the working face and so on are adopted to effectively reduce the coal oxygen composite oxidation capacity,eliminate the occurrence of spontaneous combustion of coal left in the goaf,and ensure the safety of the working face during the moving period.关键词
