20061890 Huang Yunlong (Survey Institute of Hydrologic & Engineering Geology of Hubei Province, Jingzhou, Hubei 434020, China); Shen Xiaobin Application Results of Down-hole Hammer in Surveying Water in Western Hubei Province (Rock & Soil Drilling Tunneling), ISSN 1672-7428, CN 11-5063/TD, 32(7), 2005, p.56-57, 1 table, 1 ref.)down-hole hammer drilling, air drilling Water exploration is the main project in western Hubei Province. The author’s institute has continuously worked for 4 years in order to solve shortage of water at some counties in Enshi Autonomous District. The authors replace the traditional core drilling by air down-hole hammer and speed up the exploration and construction. The experience laid the foundation for water exploration and well completion at rock stratum with down-hole hammer.
