摘要
本文就影响中深孔爆破崩矿决度若干被忽视的问题作了系统分析。并提出了相应的解决办法，实践表明这些措施对降低大块产出率效果良好。
In fan-pattern medium-to-long hole blasting operations, there are several significant factors affecting the fragment size. In these factors, although otherwise often neglected, are discussed in detail corresponding measures are proposed to reudce oversized fragments. It is shown in field that these measures have achieved good performance in cutting down the oversized boulders rate.
