Karst Water in Zhenfeng Mountainous Area of Guizhou Province and Experience in Water Exploration

摘要

Following the projects of groundwater exploration in Southwest areas of serious water shortage issued by Ministry of Land and Natural Resources in 2009, water exploration was carried out on the basis of comprehensive analysis and study of geology and hydrogeology in this area. Field investigation was conducted, and according to the landforms feature and stratum outcrop, key project spots were determined, combining with the geophysical methods to confirm the development of water-rich belt, optimize the location of holes and design the depth of holes, carry out hydrogeological drilling and pumping test for steady flow. This paper took drought-resistance wells in Zhenfeng County of Guizhou Province as successful typical examples of finding water, and briefly introduced the main methods, technical routes adopted in the water exploration and the results achieved.
