Fuzzy Evaluation of the Impact of the Open-Pit Limestone Mining on Geological Environment

Abstract:

Through the current situation survey of geological environmental disasters caused by limestone mining in Chongqing and combined with the principles of establishing evaluation index system and industry experts’ advices, we get the geological environmental impact assessment system of open-pit limestone mining which is consist of 7 dimensions and 25 indexes. Using analytic hierarchy process (AHP) to assign the weight of 25 indexes and based on membership functions of trapezoidal distribution to establish evaluation standard, the fuzzy comprehensive evaluation model is constructed. According to the principle of maximum membership degree, we get the influence degree of the geological environmental system affected by the open-pit limestone mining in Chongqing. This model makes the impact on geological environment of limestone mining quantitative and plays a certain guiding role in the local environmental protection strategy formulation and geological disaster prevention.
