摘　　要：文章结合大水头煤矿煤层自燃发火的实际,详细介绍了采用砌筑双密闭墙,墙间注罗克休泡沫封堵剂处理密闭漏风的技术方案及施工工艺,为特殊条件下快速处理漏风,提供了新的技术途径。实践证明:应用压注罗克休技术堵塞了采空区漏风通道,减少采空区漏风,消除煤层自燃隐患,从根本上达到治本的要求。In combination with a large head and the actual spontaneous combustion in coal mines,detailing the use of double-sealed masonry wall,the wall between the foam blocking agent injection Rock deal sealed off the technical program of air leakage and construction technology for the rapid processing of air leakage under special conditions,provides a new technical approach.Practice has proved that： The pressure injection technology blocked off Rock Air Leakage channel,Air Leakage reduction,elimination of coal spontaneous combustion risk,a fundamental requirement to achieve a permanent cure.
