Common Problems in Fujian Coalfield Drilling and the Treatment Measures

摘要:

福建煤田钻探中常遇坍塌、涌水、漏水、溶洞、老洞、缩径等问题，严重影响钻探质量、效率和成本。通过长期的钻探实践摸索、研究、攻关，初步形成了一套福建煤田钻探的技术工艺方法。结合一些实例，总结了福建煤田钻探中常遇问题及处理方法。

Abstract:

The collapsing, water inflow, leakage, karst cave, old cave and hole shrinking are often encountered in Fujian coalmine field drilling, the drilling quality, efficiency and construction cost were seriously affected. By the long term study on drilling practice, a set of drilling technical process was formed for Fujian coalmine field. Some common problems and treatment measures of Fujian coalmine field drilling were summed up.
