Occurrence and seepage flow types of the ore-bearing seam groundwater in Tamusu uranium deposit

Tamusu uranium deposit is a large-scale sandstone-type uranium deposit. Hydrography experiment shows discharge from drilling is great and permeability of the Ore-bearing seam is excellent. The occurrence and seepage flow types of groundwater is necessarily important factor when the project of uranium resource exploration is determined. According to study of deposit's geologic exploration date, core's observation and test results of physical character's parameter, the results show that there are several fracture tectonic and magmatic activities in the mining area. The Ore-bearing rock is hard, compact, have low water yield property, few porosity and poor permeability. The groundwater mainly consists of fissure-water, and some few pore-water. It is suggested that further study on geology and hydrography aims at the development of and the characteristics of the occurrence and seepage flow. (authors)
