药包的几何形状是固体介质爆破效果的决定因素之一．在地下矿深孔爆破中利用偏平药包可显著降低凿岩爆破费用和提高岩石破碎程度．本文介绍俄罗斯东方采矿科学研究所研究的形成相应形状空腔的工艺和钻凿缝式空腔的钻机以及在卡兹矿务局试验的情况。
The geometry of the pack is one of the determinants of the blasting effect of a solid medium. In the deep underground blasting using flattening kits can significantly reduce the cost of rock blasting and improve rock fragmentation. This article presents a study of the processes for forming cavities of the corresponding shape and drilled slotted cavities studied by the Russian Institute of Oriental and Occidental Mining and the test carried out at the Katz Mine Agency.
