摘要
采用抛物线型隶属函数分别建立了基于应力值和应力变化速度的冲击危险性指数计算公式,利用最大隶属度原则计算多因素冲击危险性指数,使用云图的方式全面、直观地反映工作面支承压力及冲击危险性的空间分布规律,最终建立了基于云图的冲击危险性预警系统.该系统已在全国20多个具有冲击危险性的煤矿得到应用,并取得良好的效果.
Two rock burst risk index functions were built based on stress and stress change rate respectively by using a parabolic membership function model.The burst risk index with multiple factors was calculated under the maximum membership degree principle.The spatial distributions of bearing pressure and burst risk of the working face were demonstrated comprehensively and directly by cloud pictures.Finally a cloud-based risk early warning system was obtained.This system had been applied in more than 20 coal mines with risk bursts and achieved good results.
