精准识别冲击危险区域并给出危险程度及其演化规律对冲击地压防治具有重要意义。采用变形局部化与多元地球物理指标空间扫描相结合的方法,探究大能量事件发生区域的微震前兆特征,追踪冲击危险区域的动态演化过程。基于变形局部化原理,利用梯度显著性指标识别变形局部化区域,圈定冲击危险区域;采用滑动窗扫描方法,研究了变形局部化区域内的
It is of great significance to accurately identify the rockburst hazard areas and give the hazard level and its evolution law for rockburst prevention and control. In this study, the method combining deformation localization with multivariate geophysical indicators spatial scanning is used to explore the precursor characteristics of microseismic in the area of high-energy microseismic events and track the dynamic evolution process of rockburst hazard areas. Based on the principle of deformation localization, the gradient significance indicator is used to identify the deformation localization areas and delineate the hazard area. The sliding window scanning method is used to study the spatial distribution characteristics of physical indicators such as
