Risk evaluation system of abnormal weighting in fully-mechanized sublevel caving face and its application
摘要
Abstract
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.关键词
