摘要
本文讨论了地下采矿中矿岩结构面的调查,统计方法,调查资料的整理和利用,天然大块率的计算公式,天然块度分布曲线的绘制方法等。并初步讨论了地下深孔爆破中三种临空面的适用情况。
The investigation and statistics of structural plane of mineral mass for underground mining , the use and statistics of investigation data, calculation of natural large block ratio and plotting of distribution curve of natural block ratio are discused in this paper. Three kinds of free surfaces of blasting for long hole under- gound blasting are preliminarily analysised as well.
