简述了陈台沟铁矿区地层的岩性及结构构造情况，总结了该矿区钻探施工所遇到的坍塌、掉块、漏水、涌水、缩径等不良地质现象所带来的施工问题，厚大千枚岩强烈造斜地层造成钻孔弯曲问题，深层钻进遇“打滑”地层等3大难题，提出了解决此3大问题的措施方法，取得了良好的效果。
簡述瞭陳檯溝鐵礦區地層的巖性及結構構造情況，總結瞭該礦區鑽探施工所遇到的坍塌、掉塊、漏水、湧水、縮徑等不良地質現象所帶來的施工問題，厚大韆枚巖彊烈造斜地層造成鑽孔彎麯問題，深層鑽進遇“打滑”地層等3大難題，提齣瞭解決此3大問題的措施方法，取得瞭良好的效果。

The paper briefly introduces the lithology and structure construction in Chentaigou iron mine, induces 3 aspects of difficultis of collapse, block falling, water leakage, water inflow and diameter shrinkage affected by bad geological condi-tions;hole bending caused by strongly deflecting formation of thick phyllite and slipping formation encountered in deep drilling.The measures and methods are put forward to these 3 problems with good effects.
