摘　　要：在详细分析影响矿井回采工作面安全生产的各种因素的基础上,从顶板压力集中水平、支架工作状态水平和管理水平3个方面构建了矿井回采工作面安全性评价指标体系,并将回采工作面的安全水平划分为4个等级:Ⅰ级安全性良好;Ⅱ级安全性一般;Ⅲ级安全性差;Ⅳ级安全性极差。同时建立了基于物元分析的综合评价方法,利用该方法对枣庄矿业集团新源井12101回采工作面生产安全性进行了综合评价,找出了其存在的主要安全问题,并提出了相应的改善对策。The factors influencing the safe production on the working faceare analyzed and a evaluation index system for safety of working face is set up, including roof pressure centralizing level, bracket working state and management level. The safety on the working face is graded into four levels： good, ordinary, bad and worst. A synthetic evaluation method based on matter element analysis is set up. Using this method, the 12101 working face in Xinyuan Mine of Zaozhuang Mine Group is evaluated, and the primary factors affecting the safety of the working face are analyzed. At the same time, corresponding countermeasures to improve the working safety are put forward.
