4% Zn) ore stockpiles. Limestone (Ca >28%) from the pit is mined for plant acid neutralisation purposes. Material with Zn <1% is designated for the waste stockpile. "Spotting" and recording of ore types and tracking of tonnages and grades, according to mining perimeters and loading plans, is undertaken inpit by a dedicated team of geology

Nonmetal Mine, Livingston County, IL: On July 11, 1990, flyrock from a limestone quarry traveled about 930 ft and fatally injured a resident who was mowing grass on his property [MSHA 1990b]. Limestone was mined from a single bench by drilling and blasting.

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.

In a copper mine this resulted in a decreased powder factor and thereby less cost for the explosive. In a limestone quarry an expansion of the drilling pattern lowered the drilling cost and the changeover to Bulk Explosive made handling and storage more adventageous. The studies are made for a surface copper mine using

The main objective of fragmentation by blasting is to achieve the optimum powder factor, which may be defined as the powder factor required for the optimum fragmentation, throw, ground vibration, etc. for a specified blast condition to minimize the overall mining cost. Presently, the powder factor is established through the trial blasts. However, powder factor may be approximated using rock, design and .
