矿山爆破效果的可拓学评价

Extension Theoretical Evaluation of Mine Blasting Effect

针对目前矿山爆破效果评价的特点,引进可拓理论对黄麦岭磷矿某台阶爆破效果进行评价。选取爆破质量、爆破安全和爆破技术经济效益3个方面作为一级评价指标,松散系数、大块率、根底率、前冲情况、后冲情况、爆破震动、飞石距离、炸药单耗和每米崩矿量等9个方面作为二级评价指标。计算结果表明:该次矿山爆破爆破质量处于良的范围内,爆破安全、爆破经济效益和最终的爆破效果都处于"优"的范围内。最后将此次爆破效果评价结果与实际情况相比较,得到其与实际情况相一致。因此,将可拓学理论运用到矿山爆破效果评价中是可行的,具有工程应用价值。

Aiming at the characteristics of mine blasting effect evaluation,the extension theory is introduced to evaluate the bench blasting effect in Huangmailing Phosphate Mine. Three parameters of blasting quality,safety and technical and eco-nomic benefits are selected as first-rank evaluation indexes. Nine parameters of loose coefficient,boulder yield,toe rate,fore-ward,backward,blasting vibration,fly rock distance,explosives specific consumption and ore caving amount per meter is con-sidered as second-rank evaluation indexes. The calculation results show that：the blasting quality is within the range of good, and blasting safety,economic efficiency and ultimately blasting effect all are within the range of excellent. Finally,comparison of the blasting evaluation results with the actual situation shows that it is consistent with the actual situation. Therefore,the ap-plication of extension theory to evaluating mine blasting effect is feasible,and has engineering application value.
