DESIGNING BLAST PATTERNS USING EMPIRICAL FORMULAS A Comparison of Calculated Patterns With Plans Used in Quarrying Limestone and Dolomite, With Geologic Considerations by Joseph M. Pugliese 1 ABSTRACT This work was done by the Bureau of Mines to provide quarry operators
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.
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
