The powder factor in blasting is expressed in pounds of explosive per what?

The powder factor in blasting is expressed in pounds of explosive per cubic yard of rock broken. This measure is crucial in mining and construction as it quantifies the efficiency of the blasting process. By understanding how much explosive is needed to break a specific volume of rock, operators can optimize their blasting procedures to ensure sufficient rock fragmentation, reduce costs, and minimize the environmental impact.

Using pounds of explosives per cubic yard provides a clear and practical basis for measuring and comparing the effectiveness of different blasting techniques and materials. It allows for straightforward calculations in project planning and can aid in achieving desired rock fragmentation sizes, which is essential for downstream processing and excavation work. This info is relevant in assessing the power of the blasting, ensuring safety standards, and achieving project objectives. The volume of rock is an important factor, as it directly correlates to the amount of explosive needed to achieve optimal results in excavation or surface preparation.
