矿山钻探应急救援中生命通道的钻井技术以山东栖霞笏山金矿事故救援1号孔为例

Drilling technology for the lifeline channel in mine emergency rescueA case study of the accident rescue of the Hushan Gold Mine in Qixia city, Shandong province

摘要:

矿山事故发生后，首先救人。如果井筒或巷道遭到破坏，救援人员要想到达井下事故现场，必须清理井筒、巷道，如清理所需时间长，危险性高，则必须果断采取地面钻井救人的方法。先钻小眼井，贯通巷道，保障被困矿工生命，包括送风、送给养、送药品、通讯等，称为生命通道；然后，钻进大眼井，实施地面钻井垂直救援，称为救生通道。以栖霞笏山金矿救援1号孔为例，介绍生命通道的钻井工艺技术。

Abstract:

After the mine accident， the first thing to do is to save people. If the shaft or roadway is damaged， rescuers must clean up the shaft and roadway if they want to reach the underground accident site. If cleaning takes a long time and there is high risk， they must decisively adopt surface drilling methods to rescue people. The small diameter borehole， also known as lifeline channel， is first drilled through to the roadway to provide life supply to the trapped miners， including air， food， drugs， communications； then， the large diameter borehole， known as rescue channel， is vertically drilled from surface for rescue. Taking the No. 1 rescue hole in the Qixiashan gold mine as an example， the drilling technology for the lifeline channel is introduced.
