摘要/Abstract

摘要： 由于提高回采上限工作面发生压架事故的复杂多样性和突发性，上提工作面压架危险性难以准确评价。在系统分析影响上提工作面压架危险状态的地质因素及指数和开采技术因素及指数的基础上，提出了上提工作面压架危险性的综合指数法分级评价方法，确定了上提工作面压架危险状态等级评定的综合指数。根据压架危险状态评定综合指数将上提工作面压架危险程度分为4 级：无压架危险、弱压架危险、中等压架危险和强压架危险，并依据不同的压架危险程度及主要影响因素提出了相关防治措施。通过工程实例对该评价方法进行了验证，结果表明该方法的评价结果与工作面实际回采情况基本一致，可应用于上提工作面压架危险性评价中。

Abstract: It was difficult to accurately assess the risk of powered support jammed in upper exploitation limitation-heightened working face due to the complexity and abruptness of powered support jammed accidents. Through system analysis of the effect factors and risk indexes caused by the geological and mining technology conditions of powered support jammed danger, a classification forecast method of powered support jammed in raise working face has been proposed with comprehensive index method, and the comprehensive index of powered support jammed has been determined in this paper. The hazard degree of powered support jammed can be divided into four classifications: no risk, weak risk, medium risk and strong risk; the corresponding preventing measures have been proposed according to hazard degree and main effect factors. According to the application results of this method in some engineering practice, the evaluation results are basically consistent with the actual situation, which proves that the evaluation method can be used in powered support jammed prediction.
