摘要
池沟矿区钻探施工中所遇到的主要问题是第四系松散层及强风化岩层厚,钻孔易坍塌,成孔困难,深部岩层结构复杂,漏失严重,导致勘查工程进展缓慢。现场及时分析原因,采取有针对性的工艺措施,有效地解决了这些问题,按期完成了施工任务。
Quaternary loose soil, heavy strong weathered rock stratum, borehole collapse, complex deep rock structure and leakage were encountered while drilling in Chigou copper mining area, analysis was made according to these problems to take the aimed measures.
