中文摘要：

矿山井下工作面环境评价对于找出当前环境存在的问题和管理环节存在的不足,进而有效整改以保障作业人员身体健康具有重要意义。针对目前环境评价方法过于依赖于专家意见和指标权重信息的问题,提出基于随机模拟法,在贫（无）评价偏好信息的情况下,对矿井井下工作面环境进行综合评价。实例应用分析表明：利用随机模拟评价法可以得到较为准确的工作面环境评价结论,且概率形式的结论信息相对绝对性评价结论更为客观和符合实际,从而可为决策者管理和制定措施提供更为丰富的依据。

英文摘要：

Mine underground working face environment assessment can find out the problems existed in the present environment and the shortcomings in the management,so the corresponding rectification can be conducted to guarantee the health of the operators. As you know,we heavily depend on experts comments and index weights in environment assessment,so the stochastic simulation is put forward,in which the mine underground working face environment is comprehensively assessed lack of assessment preferences information. The application analysis shows that more correct working face environment assessment results can be achieved by using stochastic simulation,also the probability result is more objective and practical compared to the absolute result,so it can provide more rich references for the management and measures formulating of decision- makers.
