Abstract:20世纪中叶出现的孕镶金刚石钻头，为机械式破碎岩（矿）层的钻探工程揭开了新的篇章。因其分散的切削具自动磨蚀、脱落和及时更新的特性，既减轻机械负荷，更提高纯钻进速度和回次进尺，是高效、优质、低成本的取心钻进的好办法。业内的专家、学者们不辞辛劳，在岩石破碎机理，人造金刚石单晶，孕镶人造金刚石钻头设计、制造及钻进工艺技术等方面进行了大量的探索和实践。

Abstract:As the development of city construction, more and more high-rise buildings emerge in dense down town. Due to the narrow space of engineering and dense underground pipe nets, the spaces which can be used to construct become even smaller. Meanwhile the safety of around buildings should be taken into account while excavating the foundation pit. The contracy construction method of deep foundation pit successfully resolved the problems mentioned above. The main technical peculiarities, main technical measures and their existing problems of the contrary construction method were further discussed after the working principles of the method were clarified.

Abstract:An iron ore shaft in Hebei was constructed by drilling. After removal of steel casing in the shaft, water leaked around the shaft wall. Several methods, such as filling the shaft with mud, slip casting on the bottom of shaft, lateral drilling and slip casting behind the wall of the shaft and laying an water leakage wall, were take to stop the leakage. Finally the water was blocked.
