对综合指数法中地质条件影响冲击危险性指数存在的问题进行了分析和探讨;根据平煤四矿大量现场统计资料和实测数据并运用数学分析软件,对地质条件影响冲击地压危险状态的因素及指数确定进行了改进和优化,加入了直接顶、老顶的冲击能量指数,瓦斯作用影响,距开采集中应力区距离3个地质条件影响因素,使综合指数法内容覆盖更加全面,对冲击危险性的预测更切合实际。
This paper analyzes and discusses the problems existing in the impact index of geological conditions impacting the comprehensive index method. According to a large number of on-site statistical data and measured data of Pingdingshan No.4 Mine and using mathematical analysis software, And index determination has been improved and optimized, adding direct impact, the impact energy index of the roof, the impact of gas, distance from the mining stress zone three geological conditions of the factors that make the comprehensive index method to cover a more comprehensive, the impact of the risk Sex predictions are more realistic.
