| Abstract: | The Quaternary overburden layer is thick in Wanglou iron ore area of Henan Wuyang with complex formations and breaking rocks, collapsing and diameter shrinkage easily happen, the survey drilling is difficult. According to this situation, appropriate construction process and technical measures were adopted, such as equipment selection, borehole structure, casing, bit selection and flushing fluid technology. This paper summarizes these experience. |
