煤气化工艺生产中涉及的危险有害介质可能导致安全事故，造成人身伤害和财产损失。为更好的辨识、评估煤气化企业存在的安全生产风险及其危险程度，论文采取模糊综合评价理论，选取典型的煤气化工艺——某煤气化企业煤制甲醇生产过程为研究对象，构建合理的安全风险评价指标体系，并对某煤气化企业进行模糊综合安全评价。

In the process of coal gasification, there are many kinds of raw materials and products that are inflammable, explosive, poisonous and harmful, which can cause casualties and property losses. In order to evaluate comprehensively the risk level of safety production in coal gasification enterprises, we used the fuzzy comprehensive evaluation theory and selected the coal-to-methanol process, which is a typical coal gasification process, in a coal gasification enterprise in Chongqing as the study object to construct a reasonable indexes system of safety risk evaluation, and carried out fuzzy comprehensive safety evaluation of the enterprise.
