Abstract:
To quantitatively assess the risk level of coal mining enterprises comprehensively, it provides an operational and dynamic risk assessment scheme for coal mining enterprises risk control and safety management. Firstly, considering the characteristics of coal mine accidents, a risk assessment index system of coal mining enterprises is constructed from four aspects: personnel, equipment, environment, and management, grounded in the principles of systematicity, comprehensiveness, applicability, and operability. Subsequently, based on the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE), an AHP-FCE method for risk assessment of coal mining enterprises is proposed. Finally, leveraging coal mine case analysis and employing digital processing techniques for raw qualitative data, quantitative assessment, and analysis of the overall risk level of the coal mining industry are achieved. The significance of our proposed risk assessment scheme is manifold. Firstly, it can be used for risk assessment of the same coal mine during the same period to assist in the effective implementation of coal mine safety management. Secondly, it can be used for risk assessment of the same coal mine during different periods. If risk assessment work is conducted quarterly, comparisons can be made between quarters to track changes in coal mine risk over time. Thirdly, it can also be used for comparative analysis of risks between different coal mines. If applied to risk assessment work of different coal mines during the same period, it can compare the risk management work of different coal mines to serve as an incentive. Additionally, if corresponding changes are made to the risk assessment index system, the proposed risk assessment scheme can also be applied to other industries.
