区域安全评估模型在煤矿安全管理中的应用研究

Research on the application of area safety assessment model in coal mine safety management

当前煤矿安全监测和管理系统的安全评价粒度基本都是矿井级或子系统级,无法针对矿井的不同区域进行精细化管理。针对该问题,基于矿井各区域作业场景特点,面向安全风险评价提出了一种统一的区域划分方法,将风险、隐患、灾害与区域工况、设备维护管理及人员定位等信息结合,对各安全系统数据进行统一区域划分和整理;从人、机、环、管4个维度对安全指标体系开展综合评价,通过主观赋权和客观赋权相结合的方法计算区域安全评估中的各指标权重,主观赋权通过层次分析法实现,客观赋权法采用熵权法实现;构建区域安全评估模型,对煤矿当前安全情况进行定量化评估和等级划分,采用归一化融合权重计算基础安全评分,并考虑高风险组合、历史趋势变化及区域间耦合影响对评分进行修正,得到矿井各级区域的综合安全评分。该模型已成功应用于陕西小保当矿业有限公司的智能化综合管控平台,为准确评估煤矿井下安全风险、提高煤矿安全管理水平提供了有效参考。

The safety evaluation granularity of the current coal mine safety monitoring and management system is basically at the mine level or subsystem level.It cannot be finely managed for different areas of the mine.In order to solve the above problem,a unified area division method is proposed for safety risk assessment based on the features of operational scenarios in various areas of the mine.This method combines information such as risks,hidden dangers,disasters with area operating conditions,equipment maintenance management,and personnel positioning to unify and organize data from various safety systems.A comprehensive assessment of the safety indicator system is conducted from four dimensions:human,machine,environment,and management.The weights of each indicator in the area safety assessment are calculated through a combination of subjective and objective weighting methods.The subjective weighting is achieved through the analytic hierarchy process,while the objective weighting method is achieved through the entropy weighting method.The method constructs an area safety assessment model,which quantitatively evaluates and classifies the current safety situation of coal mines.The method uses normalized fusion weights to calculate the basic safety score,and considers high-risk combinations,historical trend changes,and inter regional coupling effects to modify the score.The comprehensive safety scores of all levels of coal mine areas are obtained.This model has been successfully applied to the intelligent comprehensive control platform of Shaanxi Xiaobaodang Mining Co.,Ltd..It provides effective reference for accurately evaluating underground safety risks in coal mines and improving the level of coal mine safety management.
