Abstract:

Multi-objective land reclamation model of coal mine is an effective way to improve the overall efficiency. Besides irrigation water for farmland reclamation, the multi-objective water resources supply and demand balance is needed to be addressed. The author used dynamic programming (DP), water supply and demand balance of multi-objective land reclamation had been studied in mining area. The author took water supply and demand balance of multi-objective land reclamation of Xuzhou Jiuli mine example, through the objective function was established, law in reverse order from the end of stage, on the order to solve of the problem of various single-stage optimization, the best decision of water demand and supply was obtained. Water supply and demand balance of multi-objective land reclamation and the maximizing effectiveness can be solved by this method, the multi-objective reclamation of coal mine area was effectively promoted.
