摘　　要：以神东矿区补连塔煤矿22307综采工作面为案例,分析了浅埋深超大面积采空区综采工作面低氧现象产生的原因,分析认为采空区与综采工作面之间时刻处于一种多元动态平衡的状态,打破平衡最直接的因素是大气压变化。对前期防治的一些引流、卸压等技术及其效果进行评估,发现其防治效果不是很理想;重点对均压通风技术的实施及防治效果进行介绍,结果表明:在众多低氧防治措施中,均压通风技术对低氧防治效果最为理想。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 [urge-area goal 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 teehnology and their effect and find that the effects are not very ideal. We focus on the implementation and control effect of pressure balanee 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.
