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。
Determine the abnormal pressure to the danger zone is the implementation of abnormal pressure control measures to the premise. The factor of induced abnormal pressure in the fully mechanized top coal caving face was statically analyzed and the risk assessment factor of abnormal pressure was determined. The risk index was used to characterize the dangerous degree of abnormal pressure in stope and the risk assessment model of abnormal pressure in fully mechanized top-coal caving face was established. Language development of abnormal pressure to the fully mechanized top-coal stowage risk assessment system. The coal seam fully mechanized caving face in Shandong coal seam pressure accident risk assessment as an example for application, the evaluation results and the actual good, provides a method for the risk assessment of abnormal pressure to the fully mechanized caving face.
