摘要
基于地质动力区划方法,首先确定区域内的活动断裂,划分岩体断块结构,结合原地应力测量结果,用数值计算方法来确定区域岩体的原地应力分布状态,根据原地应力的分布特点对研究区域潜在的有发生动力现象危险的地点进行区域预测。经多个矿区的研究实践,表明该方法预测较为准确,成为矿井动力现象区域预测的一个新方法。
Based on the Geodynamic division method, firstly the active faults are determined and the blocks of rock mass are divided and then combined the insitu stress measurement, the stress distribution of rock mass is simulated by numerical calculation. According to the stress distribution, the regions that mine dynamic phenomena maybe occur are forecasted. This method has been proved to be comparatively accurate after it is used in several mines, and it becomes a new approach to regional forecast on mine dynamic phenomena
