| Abstract: | According to the problems of ChangCun ore such as the big gas emission of N3-3 slowly inclined coal seam longwal,the gas overrun of upper corner,this paper analysed the gas source and migration rule,finded out the cause of the poor effect on gas control working on uplink ventilation,studied and implemented the downside ventilation mode,cooperated with the measures which extracted goaf gas through roof fracture zones high drilling,improved the gas treatment effect,eliminated the gas overrun on working plane the top corner,realized the high high productivity and the safety. |
