| Abstract: | 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. |
