Abstract
At present, the easily mineable coal resources have been depleted in China, and it is very necessary and urgent to mine under hydraulic projects for continuous production and sustainable development of the society. In this paper, the coal field of Shenjiazhuang Colliery, which mostly lies under the Yuecheng reservoir area, is studied. By using a comprehensive study involving field engineering geologic survey, indoor rock mechanics test, in situ test, statistical analysis of mine well discharge, water quality analysis, theoretical calculation and numerical simulation, it is concluded that coal mining would not affect safe operation or bring any secondary geological hazard to the reservoir area. This paper provides an important scientific basis for achieving double profits for both departments of water and coal resources and helping departments related make further decisions. In addition, the research reported in the current paper can be served as a reference for similar projects, such as the coal mines under the Xiaolangdi reservoir area, under the Xifeihe Dam and under the mid-route South-to-North Water Transfer Project.
