| 中文摘要:目前，大直径钻孔救援技术多用在矿井发生事故后的快速紧急救援，属于“事后”被动等待救援，为实现传统的被动等待救援向积极自主逃生转变，将大直径救援钻孔与矿井避难硐室结合，提前构建灾害应急逃生系统。结合大直径单人救援钻孔在某煤矿避难硐室应急逃生系统中应用实例，分析了救援钻孔的布置、结构设计原则，重点研究了救援钻孔的成孔方法选择、分级扩孔工序、钻进参数、钻井液工艺、成井设备等钻探技术，并对大直径救援钻孔的适用条件进行了研究，研究成果可为类似矿山实施大直径单人救援钻孔提供借鉴和参考。 |

| Abstract:At present， large-diameter borehole rescue technology is mostly used for rapid emergency rescue after the mine accident， which belongs to “post-event” passive waiting for rescue. In order to realize the transformation from traditional passive waiting for rescue to active and independent escape， the large-diameter rescue borehole is combined with the mine refuge chamber to build the disaster emergency escape system in advance. In relation to a field case of large-diameter man-wide rescue borehole drilling for the emergency escape system of the refuge chamber in a coalmine， the layout and structural design principles of rescue drilling are analyzed with focus on the selection of the drilling method， the sectional reaming process， drilling parameters， drilling fluid technology， well completion equipment and other drilling technologies， as well as the applicable conditions of large-diameter rescue drilling. The research results can provide reference for the implementation of large diameter man-wide rescue borehole drilling in similar mines. |
