摘　　要：为了保证云冈煤矿8617工作面不因自然发火而影响正常生产,针对该工作面特点,开发了大掺量粉煤灰灌浆固化膨胀充填技术,对该工作面开切眼、正常回采、末采及撤架期间进行预防性防火灌浆,通过对8617工作面生产过程中进行指标气体检测,检测结果表明工作面煤层氧化缓慢、无自燃现象,该项新技术为今后煤自燃防治提供了技术指导。In order to ensure the Yungang Mine 8617 working face is not due to spontaneous combustion and affect the normal production, according to the characteristic of the working face, the development of the high volume fly ash grouting solidification expansion filling technique on the working face, cut open during normal mining,mining, end and withdrawing support preventive fire grouting, the index of gas detection by production of 8617 working face in the process, test results show that the oxidation of coal working face slowly, without the phenomenon of spontaneous combustion, the new technology provides technical guidance for the prevention and control of coal spontaneous combustion in the future.
