摘要
利用灰色关联度理论研究几种典型矿岩与岩爆倾向性有关的一些力学参数同两个常用的岩爆倾向性指标———弹性能指数和冲击能指标的关系 ,参数包括岩石单轴抗压强度、压拉比、脆性比、脆性系数和单位极限储能。利用灰色关联度计算模糊综合评判时的权系数 ,综合考虑影响岩石岩爆倾向性的几个关键参数 ,对这几种矿岩的岩爆倾向性进行综合评判 ,得出这几种典型矿岩岩爆倾向性相对大小。研究结果对岩爆危险区域的划定具有实用意义。
The relationship of two rock bursting tendency indexes-elastic energy index and impact energy index to four mechanical parameters including monaxial compression strength,ratio of compression strength to tensile strength,brittleness ratio,brittle coefficient and maximum storage energy of unit volume,is investigated by using gray relation degree analysis The synthetical evaluation of rock bursting index of the typical rocks in a certain deposit is conducted,and the order of rock bursting tendency is obtained by calculating weight factors using fuzzy mathematics,integrative consideration of key parameters affecting rock bursting tendency The result is applicable to plot out possible rock bursting area
