摘要

本文给出了石灰石采石场控制细粉生产的爆破试验结果。研究表明，通过将装药系数降低到最佳值，并采用特定的炮眼几何形状，可以将颗粒保持在最低限度。然而，地质特征限制了罚金的减少。

Control of fines through blasting design at a limestone quarry

Given in the paper are the results of experimental blasts in a limestone quarry for control of production of fines. The study indicated that fines can be kept to a minimum by reducing the charge factor to an optimum value, and by adopting a particular blasthole geometry. However, geological features imposed a limit on the reduction of fines.
