Abstract
Water area are widely scattered on the ground in high underground water coal mining area. In order to give consideration to both water resource and min ing subsidence land utilization, and improve the ecological environmental condition, the feasibility of constructing plain reservoir in subsided land is discussed from asp ects of technology and economy, according to literature review and field investigation.Furthermore, the framework, process and model for reservoir construction in minin g subsidence induced water area are proposed. And a case study of the practice of plain reservoir construction in the coal mining subsidence basin of Zhangji Mine in H uainan, Anhui Province is carried out. The results show that the active plain reservoir construction can improve the land reclamation rate, increase reservoir capacity an d save the reservoir construction cost, and has a good prospect and application prospect.
