矿区水文长观孔固井施工工艺研究

Study on cementing technology for long view hole in mining area

水文长观孔施工过程中,固井质量的好坏直接影响水文地质资料的准确性。尤其是煤田水文孔固井质量的好坏,直接关系煤矿的安全生产。用一般常规止水方法很难保证永久止水质量。本文主要介绍孔底注浆逆止阀塞制作及应用。

During the construction of long hydrological observation hole,the quality of cementing directly affects the accuracy of hydrogeological data.In particular,the quality of cementing in coalfield hydrology is directly related to the safe production of coal mines.It is difficult to ensure the quality of permanent water seal by conventional conventional water stopping methods.This paper mainly introduces the manufacture and application of check valve plug for hole bottom grouting.
