Comprehensive Evaluation of Mine Pressure Monitoring System in Meihuajing Coal Mine Based on Unascertained Measure Theory
To better emphasize the analysis of the overall status of the mine,particularly focusing on the function-ality and safety of the mine's uncertain mine pressure monitoring system,various potential uncertain measurement information within the mine's uncertain mine pressure monitoring system was analyzed.The goal was to identify the influencing factors that might impact the functionality and safety of the mine pressure monitoring system.Each mine's evaluation system for the safety of the mine pressure monitoring system was determined.Initially,the uncertain measurement information in the evaluation index system of mine pressure monitoring function and sys-tem safety was analyzed using uncertain measurement theory and methods.The Analytic Hierarchy Process(AHP)was employed to establish the confidence and weight of each level of measurement evaluation index.Subsequent-ly,accurate computation of the confidence vector for each level of measurement evaluation index was conducted using uncertain measurement theory,resulting in the identification of unidentified or identified measurement eval-uation index vectors.This process led to the establishment of an uncertain measurement analysis model.Finally,based on the recognition of the uncertain confidence vector,the confidence level and evaluation index level for each mine regarding the safety of the mine pressure monitoring system were determined.The uncertain model constructed in this study was extensively applied in the mine pressure monitoring and evaluation system of the Meihuajing Coal Mine.Field research results demonstrated that the safety evaluation results obtained by using this model aligned with the actual on-site situation.
