| 中文摘要:2021年1月10日下午2点，位于山东烟台栖霞市的山东五彩龙投资有限公司笏山金矿井下240 m发生爆炸事故，造成井下22名工人被困。事故应急救援指挥部首批布设了4个救援孔，山东省地质矿产勘查开发局第六地质大队承担了3号救援孔的施工任务，采用“潜孔锤钻进+高精度测斜+套管护壁止水”的施工方案，快速钻进至521 m。之后配合国家矿山应急救援大地特勘队采用定向钻进技术完成剩余60 m施工任务，实现第一个透巷并收到井下被困矿工的回应。本次成功救援，开创了一种接力钻探救援的新模式，为矿山救援工作提供了借鉴与思路。 |

| Abstract:At 2 pm. on January 10，2021， an explosion occurred at 240m underground of Hushan gold mine of Shandong Wucailong Investment Co.， Ltd. in Qixia City， Yantai， Shandong， resulting in 22 workers trapped underground. The Accident Emergency Rescue Headquarters deployed four rescue boreholes in the first batch. The 6th Geological Brigade of Shandong Bureau of Geology and Mineral Exploration and Development undertook the construction task of No.3 rescue hole. The construction scheme of “DTH hammer drilling+high-precision inclinometer+casing wall protection and water stop” was adopted to quickly drill to 521m. Then， cooperate with the national mine emergency rescue geodetic survey team to complete the remaining 60m construction task by using directional drilling technology. The first one penetrated the roadway and received a response from the trapped miners underground. This successful rescue has created a new model of relay drilling rescue and provided reference ideas for mine rescue work. |
