中文摘要:长白沿江矿区钻探施工中遇到的主要问题是煤系地层水化膨胀，形成陷塘，钻孔坍塌、掉块，深部灰岩蚀变，形成溶洞，严重漏失，导致施工周期延长，现场及时分析原因，采用针对性的工艺措施，成功地解决了上述问题，圆满地完成了矿区施工任务。

Construction Technology of ZK0902 Exploration Hole in Yanjiang Mine of Changbai in Jilin
Abstract:Hydration swelling in coal measure strata with subsidence pool forming was the main difficulty in drilling construction in Yanjiang mine of Changbai; and hole collapsing, block-falling and deep limestone alteration formed karst cave with serious leakage and long construction period. Field analysis was made to solve the above problems by specific technologies.
