| 摘 要： | 根据冲击地压发生的地质条件,建立赵楼井田首采区综合指数法数学模型。由相邻矿区已发生冲击地压的矿井资料对数学模型进行回归拟合,确定冲击地压的分区阈值。以此数学模型对首采区内所划分的247个单元格进行了冲击地压指数计算。根据计算结果,对首采区进行冲击地压危险性分区:危险区主要分布于具有Ⅰ、Ⅱ类顶板条件,喜山期断层、褶曲分布密度较大的区段;相对危险区主要分布于构造条件较简单、具有Ⅰ、Ⅱ类顶板条件,或构造条件较复杂的Ⅲ类顶板区段;相对安全区主要分布于Ⅳ类顶板区段或构造条件简单的Ⅲ类顶板区段。

| Abstract: | According to the geological conditions of the rock outburst occurred,the numerical model of the comprehensive index method for the first mining block in Zhaolou Minefiled was established.The mine information of the mine rock outbursts occurred in the adjacent mining areas was applied to the regressive fitting of the numerical model for the determination on the subarea threshold value of the mine rock outburst.The numerical model was applied to the calculation of mine rock outburst index for the 247 element ... |
