摘　　要：采空区是紧邻回采工作面一片充满陷落岩石的非活动空间,由于陷落岩石的非规则性,冒落堆中存在着许多大小不一的漏风通道,漏风量较大。另外,采场进风巷及采空区与邻近采空区连成一片,构成比较复杂的漏风型式,给矿井"一通三防"管理等带来安全隐患。本文结合济宁二号煤矿对采空区防漏风的实践,提出了一系列有效的防止大面积采空区漏风的技术措施,为矿井的安全生产起到了积极作用。Mined areas are adjacent stope a full,inactive space rock fall,because the fall of the irregular nature of rock, take off the heap,there are many different sizes of air leakage channels,a large amount of air leakage.In addition,the stope into the wind,Lane and adjacent gob together into one to form more complex leakage type,give mine a pass three anti tremendous security risk management.In this paper,Jining II coal mine gob leak -proof wind on the practice of the process,made a series of effectively preventing large area gob technical measures for mine safety production has played a positive role.
