| 摘 要： | 通过室内试验和现场测试，获取了大量相关的试验数据，对波阻抗、爆破性指数等9个参量进行了测定，分析探求了这9个参量之间的内在相关性。认为在通常情况下．可通过测试波阻抗值对矿岩的可钻性进行初步评价。根据波阻抗值将矿岩的软硬程度分为7级。得出了92号矿体易爆难凿的结论。

| Abstract: | Through the laboratory and field tests, the measurements of such 9 parameters as wave impedance, blasting index have been carried out, so that a large number of tested data have been obtained. The internal relations of the 9 parameters have been analyzed. It is considered that the tested values of wave impedance can be used to preliminarily evaluate the drillability of ore/rock, and the hardness of roe/rock can be classified into seven levels. A conclusion is drawn that the ore/rock of the No.92 orebody is easy to blast but difficult to drill. |
