摘要:

从工程应用角度出发,选取岩石坚固性系数f、岩石的波阻抗、炸药消耗量和岩体平均裂隙距作为煤矿岩巷岩体可爆性分级的评判指标,运用层次分析法确定各影响因素的权值。通过扩展的最小二乘法准则构造目标函数,建立灰色关联模型对岩巷岩体可爆性分级进行评判。实际工程应用表明,分级评判结果较符合实际情况,对于煤矿岩巷的快速、安全掘进具有一定参考价值。

Abstract:

Based on the engineering application, this paper chooses rock consistence coefficient f, impedanee of rock, explosive consumption and the average crack spacing of rock mass as the judging indexes of coal rock explosive mass classification. Using AHP to determine weights of these four indexes. Evaluation the rock mass blasting classification by constructed the objective function though extending the least squares criterion and building grey correlation model. The result of actual engineering application shows that the grading evaluation result conform to the actual situation. And this has a certain reference value for the fast and safe excavation of coal mine roadway.
