Abstract: The water pressure test is frequently used in examination boreholes by the Guiyang Branch of the China Aluminum Company for examination of results of the weimuzhujiang the technique in attempting to prevent the alkaline water leakage from a waste water processing field. As the requirements for preventing the leakage of the alkalina water are higher and higher, the current method can not satisfy the examination requirements for checking the leakage degree after guanjiangweimu. More advanced and comprehensive new examination methods are needed for this purpose. This paper presents a comprehensive examination method which combines water pressure test, electro-magnetic CT and cross-hole resistivity techniques to examine the reliability of the weimuzhujiang.
