Prediction of water resource carrying capacity by the analytic hierarchy process-fuzzy discrimination method in a mining area

Abstract

The problem of water damage caused by coal mining has been a widespread concern in all sectors of society. Research into carrying ability relations of coal mining and water resources in mining areas is the foundation to solve this problem. It is also important to evaluate the sustainable development of mining areas as well as explore aquifer-protective mining. Based on the analysis of the characteristics and connotations of mining area water resource carrying capacity (MAWRCC), the fuzzy synthetic discriminant method is used as the evaluation method, and water resource carrying capacity (WRCC) as the evaluation standard. The evaluation system of MAWRCC under a mining action is constructed, and the main influencing factors and subordinate functions of MAWRCC are analyzed. Also, the membership degree of the influence factor is calculated. Methods for the rationality and influence factors of reliability are proven in the Shendong and Yili mining areas. They predicted the state of WRCC of the Yili mine for the next three years, under the conditions of carrying out or not carrying out aquifer-protective mining. According to the calculation results, the parameters of coal mining are the initiating factor caused by MAWRCC. Aquifer-protective mining is an effective measure to control the WRCC. The research results have important reference value and academic significance for the evaluation of MAWRCC.
