摘　　要：确定异常来压危险区是实施异常来压控制措施的前提。统计分析诱发综放采场异常来压的因素,确定异常来压危险性评价因子;采用危险指数表征采场异常来压危险程度,建立综放采场异常来压危险性评价模型;采用现代编程语言开发了综放采场异常来压危险性评价系统。以山东某煤矿综放采场异常来压危险性评价为例进行应用,评价结果与实际吻合较好,为综放采场异常来压危险性评价提供了一种方法。Determination of abnormal weighting risk zones is a prerequisite for implementing meas-ures to prevent abnormal weighting. In this paper, on the basis of statistical analysis of factors inducing abnormal weighting in fully-mechanized sublevel caving face, the factors for risk evaluation of abnor-mal weighting were selected, and risk index was used to characterize risk level of abnormal weighting in coal face. In addition, risk evaluation model of abnormal weighting in fully-mechanized sublevel caving face was established, and the system for abnormal weighting risk evaluation was developed us-ing a modern programming language. An application example was presented in one coal mine of Shan-dong province;the results agree well with the practice. A new method is provided for risk evaluation of abnormal weighting in fully-mechanized sublevel caving face.
