Feasibility analysis of lateral water interception curtain in loose aquifer during deep coal seam mining in Yushen mining area by Chunhu ZHAO, Shidong WANG, Zhongkui JI, Kaipeng ZHU, Xiangyang LIANG

“…Yushen mining area is the main mining area of the coal base in northern Shaanxi at present. During the development of high-intensity coal resources, the problems of coal seam roof water disaster and water resource leakage are prominent. with the comprehensive promotion of the ecological environment protection strategy in the Yellow River Basin, advanced, proactive, and source oriented geological guarantee requirements have been put forward for mine water prevention and water resource protection. the article focuses on the problem of water inrush (loss) in the loose water bearing layer near the surface under the influence of underground coal mining in Yushen mining area, Shaanxi Province. …”
