Stability Evaluation of Coal-mining Area based on Analytic Hierarchy Process and Multi-level Fuzzy Mathematics Method
On the basis of practical datas of a mined-out area in No.6 Pingdingshan coal mine,11 main factors were analyzed.Due to the interaction among these factors,mined-out area stability evaluation index system was established.Two-level comprehensive evaluation model was set up by using multi-level fuzzy mathematics method,and weights of each factors were confirmed with analytic hierarchy process.The stability of this mined-out area was evaluated,and the results were close to the reality.It provides reference and basis for mined-out area control.
