摘要
Abstract
In Waijidi mining area, the formation is complex with broken rocks.At the early stage of drilling construction, there is common existence of coring difficulties in shallow gossan type orebody, borehole curvature degree measuring, high requirements of environmental protection for flushing fluid preparation.Drilling scheme for complicated formation was made according to the geological and construction conditions, and based on the geological characteristics of exploration target, drilling process and operation were improved to meet the needs of geological work, enhance the reliability of the geological information and ensure the realization of mining exploration target.关键词
