Abstract
Taking 22307 fully-mechanized working face in Bulianta Coal Mine of Shendong Mining Area as an example,we analyze the reasons of low oxygen phenomenon in shallow-buried depth and large-area goaf of fully-mechanized working face,and think that the goaf and fully mechanized working face is in a state of a multivariate dynamic balance all the time,and the direct factor to break the balance is the change of atmosphere pressure.We evaluate some early control measures including drainage and pressure relief technology and their effect and find that the effects are not very ideal.We focus on the implementation and control effect of pressure balance ventilation technique.The results show that pressure balance ventilation technique has ideal effect on the low oxygen control among low oxygen prevention and treatment measures.关键词
