摘　　要：岩心钻探是对地质勘探重要验证手段,是获取地球深部物质、了解地球内部信息的最直接、最有效、最可靠的方法,钻探的工作质量和效率直接影响找矿效率和效果。岩心钻探施工过程中常由于作业人员操作不当、工艺技术方法不合适、设备材料维护不到位等人为因素,或钻遇复杂地层、工器具质量问题等客观外界因素,发生卡钻、断钻、烧钻、埋钻、涌水、漏失等孔内事故,处理不恰当会引发较大的财产损失甚至人员伤亡事故。Core drilling is an important verification method for geological exploration.It is the most direct,effective and reliable method to obtain deep earth materials and understand the information of the earth's interior.The quality and efficiency of drilling work directly affect the efficiency and effectiveness of prospecting.During the core drilling construction process,it is often due to human factors such as improper operation by operators,improper technology and methods,inadequate maintenance of equipment and materials,or objective external factors such as complex formations,quality problems of tools and tools,etc.,resulting in stuck,broken,and burnt drills.In-hole accidents such as burial drill,water gushing,leakage,etc.,improper handling can cause large property losses and even casualties.
