The assessment of emergency capability of coal mines based on AHP-fuzzy comprehensive method

In order to improve emergency management capabilities and the prevention and control of major accidents, it is important to study various methods for the assessment of the emergency capabilities of coal mines. This paper aims to bring about an analytic hierarchy process (AHP) and fuzzy comprehensive method to assess the emergency capabilities of coal mines. Firstly, the key elements of the emergency management for coal mines are analyzed based on the theories of the emergency management. From the precaution, response, and recovery aspects, the assessment index system of the emergency management capabilities for coal mines is built and the basic indexes of each element are confirmed and discussed. Furthermore, a multi-level fuzzy comprehensive evaluation model for mine emergency management capability is built based on the AHP (Analytic Hierarchy Process) and fuzzy mathematics. The assessment index system and mathematical model are applied to a selected mining enterprise whose assessing result was "high". Some shortcomings of the emergency system of the coal mine were analyzed and some suggestions were proposed to improve the emergency capabilities for the coal mine. The study is helpful for emergency management and the prevention of major accidents in coal mines.
