Research on Mine Geological Risk Assessment Based on Analytic Hierarchy Process
This article analyzes and studies risk management theory to determine risk identification methods.We have identified the geological environmental risks in the Jingxian mining area and its surrounding areas,and established a geological risk assessment system for mining areas in Jingxian.This system includes three criteria layer factors:ground subsidence,soil erosion,and mine collapse,as well as 12 indicator layer factors.Using the Analytic Hierarchy Process,the relative importance of each factor to the superior indicators is analyzed,and the composite weights of each evaluation factor are ultimately determined.Based on the calculation results,the geological environment risk of the Jingxian mining area and its surrounding areas is within the range of moderate risk,and the ore geological risk level is III.Measures should be taken to control the occurrence of risks.
