###### Abstract
In recent years, with the continuous promotion and application of safety system engineering in coal systems, the research on the safety evaluation of coal mines has attracted the attention of more and more Chinese scholars, and many research results have been achieved. In this regard, the three-step coal mine accident safety evaluation method (which is a branch of the index method), the accident tree method and safety countermeasures, the comprehensive evaluation index method of coal mine safety production status, and the gray system method were put forward successively. These achievements greatly promoted the application of safety evaluation in the coal industry. However, Chinese scholars have mainly focused on the rockburst mechanism, monitoring and forecasting methods, and prevention and control measures. There is little discussion on the risk of rockburst, and a systematic safety evaluation method of rockburst has not been formed so far [29; 30; 31; 32]. In the past, some scholars put forward experience category analysis, methods of drilling cuttings, and methods of determination of moisture content to perform the relevant evaluation. These methods have attained some applications; however, they are often only static index reflecting methods that cannot dynamically reflect the influence of the various indicators of evaluation results of percussive ground pressure. Thus, the results of these methods are accompanied by certain errors, affecting the scientific decisions of coal enterprises [33]. The mechanism of rockburst is very complicated, and there are many influencing factors. It is necessary to choose a reasonable evaluation method to make an effective comprehensive evaluation of the various factors of shock hazard. This is needed for correct measuring of the degree of shock hazard and for providing a reference for the formulation of prevention and relief measures [34; 35]. In this paper, an innovative and reasonable evaluation method is proposed to solve the problem of the imperfect evaluation method of coal mine safety, especially in the aspect of rockburst risk evaluation, aiming at the effective comprehensive evaluation of various factors of impact hazards. This method introduces the concept of dynamic evaluation and reflects the changing trend of rockburst risk in time by establishing a dynamic evaluation system, so as to improve the accuracy and comprehensiveness of the evaluation method. Compared with the traditional evaluation method, which can only reflect the method statically, this method can comprehensively consider the influence of various factors on the evaluation results of rockburst, making the evaluation results more reliable. Based on the concept of shock pressure, this paper discusses the relationship between microseismic events and their energy and frequency, and introduces the \"double high\" phenomenon as the top event. Each evaluation index was considered as the basic or intermediate events. Furthermore, the accident tree, the analytic hierarchy process, and the fuzzy comprehensive evaluation model were adopted to determine the weight of each evaluation index. The fuzzy comprehensive evaluation method was used to evaluate each index comprehensively, to divide the danger level, to put forward the safety response measures, and to evaluate the effectiveness of prevention and control measures. The existing impact risk evaluation methods mostly include the empirical analogy analysis method, method of drilling cuttings, and acoustic emission method [36]. The common disadvantage of these methods is that a single index is employed as the impact risk evaluation index, which may bring significant errors to the impact risk evaluation results and thus can affect the safety decisions of coal mining enterprises [37]. Therefore, it is necessary to comprehensively consider the impact factors of rockburst and to apply the relevant theories of a comprehensive evaluation to establish a comprehensive evaluation model for rockburst risk.
