贵州地质探矿工程技术发展综述

Summary about the Development in Exploration Engineering of Guizhou Province

贵州地矿局十年来探矿工程技术的蓬勃发展，取得了一系列令人瞩目的成就。发展了以金刚石绳索取心钻进，冲击回转钻进，受控定向粘进，空气钻进等多种工艺钻探技术方法和以低固相、无固相等多种优质钻井液及护孔堵漏技术，并研制和推广了多种配套技术，其成果共３０余项。形成了以金刚石绳索取心为主体的多工艺钻探体系；以低密度钻井液为主体的护孔、堵漏、保矿技术体系；以坑探机械化，光面爆破，锚喷支护为主体的掘进技术体系的发展方向。这些技术的推广应用，为地质找矿和开拓地质市场提供了可贵的经验，改革开放也为这门技术开辟了广阔的前景，对国民经济建设将做出新的贡献。

In the past ten years, many great achivements in exploration engineering have been made in Guizhou Bureau of Gology and Mineral Resources, including such drilling techniques as diamond drilling with wireline coring, percussive-rotary drilling, controlled directional drilling, and air drilling, as well as quality drilling fluid with less and non-solid phase and protection of hole against leak. In additon, a variety of complete techniques of exploration engineering up to 30 items has also been developed and spread. As a result, a multitechnological system of diamond drilling with wireline coring combined with other drilling technology, a system of less density drilling fluid against leak and for protection of hole and core, and a system of the driving techniques with mechanical pitting, smoothy blasting and shotcrete-bolt support have been formed, which will provide many valuable experiences for their application to geological exploration and engineering in our economic construction.
