China is a country where the main source of energy is coal, the healthy development ofthe coal enterprises plays an important role in China’s economic growth. In recent years,China’s coal enterprises has developed quickly under the driven economic development,however, since the outbreak of sub-prime mortgage loan crisis in the United States,increasingly dynamic external environment and complexity of internal enterprise force themto face various risks. How to effectively identify, evaluate and prevent these risks is a hotissue which is the popular concern of the business circles and academic fields ,and whichneeds resolved. In view of this, based on systematically reviews related to existing researchresults of enterprise risk management, according to the characteristics of the coal businessrisks, this paper comprehensively uses the knowledge of mathematical statistics, correlationmethods of structural equation modeling (SEM),and correlation theories on fuzzymathematics theory to study identification and assessment of the China’s coal businessrisk,thendiscussesriskprevention,andmakesthefollowingmainresults:(1)Onthebasisoftheliterature,combinedwiththecharacteristicsofthecoalenterprises,we analyze and put forward corresponding research hypotheses from six dimensions onpotential risk factors of the coal enterprises, including the external environment, enterpriseresources, capabilities, organizational management, security and operation. we use factoranalysis and regression analysis to test the research hypotheses, whereby, identify sevenaspects of the risk factors as the keyrisk factors of the coal enterprises, consisting of policiesand regulations, industry market, critical resources, core competencies, organizationalmanagement,security,productionandsales.(2) Based on the identification of key risk factors in the coal enterprises, combined withthe existing research, we propose the coal enterprises of risk path relationship concept model and twenty two role relations hypotheses,then use structural equation modeling (SEM)method to verify concept model and research hypotheses, Accordingly, we point out sevenaspects of the key risk factors on the overall ranking of risk effect in the coal enterprises.organizational management > core competences > production and sales > critical resources >security > policies and regulations> industry market. These results provide an effectivereferencetoriskprevention.(3) Based on critical risk factors identification in the coal enterprises, we establish coalbusiness risk assessment index system, through using fuzzy comprehensive evaluationmethod on the basis of triangular fuzzynumbers to determine weight, then deduce the weightof the risk index and the level of risk rating, and measure the overall risks condition of thecoal enterprises. By analyzing, we conclude that our current coal enterprises has low level ofrisk in policies and regulations, industry market area, normal level of risk in the criticalresources, core competencies, organizational management , high level of risk insecurity,productionand sales. Thesereferthat wholesituationofthecoal enterprises is underthe general risk level . Assessment methods and evaluation results provide a basis for riskpreventiontothecoalenterprises.(4) Based on analysis of the coal enterprises in the traditional method of risk preventionand disadvantages, we design dynamic risk associated with the trigger model, then establish adynamic risk prevention system in the coal enterprises. Various risks of the coal enterpriseswere divided from the aspects of the amount and degree of risk control, thus forming fourtypes of risk portfolios to provide a basis for risk control in the Coal enterprises .we discusspath analysis as the main analysis method of risk control, and point out the steps of it, thenanalyze major initiatives of risk control and risk management in the coal enterprises .throughimproving risk prevention awareness and strengthening safety management, we suggestgeneralmeasuresonriskpreventioninthe coalenterprises.The above-mentioned researches further deepen and improve the related theories on riskmanagement of the coal enterprises, and make the coal enterprises guard against risks, seizeopportunities, meet challenges, ultimately provide theoretical guidance and decision-makingtorealizehealthyandrapiddevelopment
