Open Pit Construction Processing Design

Reasonable open pit stone construction processing design will help processors to improve production efficiency and reduce the human and financial costs. If you want to obtain more information about stone processing and mineral beneficiation plant, please really feel free to contact us. We are glad to present a service to you. Here is the main point of the design of open pit mining:

This is the maximum depth in the mine that it's going to reach in the finish of its life. This can be decided by economic factors and a breakeven point is decided beyond which it really is not economical to continue production. As this depends on economic conditions, a mine closed in 1980s can become financial now, as happened inside the case of Copper Mountain Project.

The bench height is usually decided by the financial attain on the mining equipment utilized inside the mine. As a thumb rule, a bench height is equal towards the financial bucket height of an excavator (like shovel or loader) plus three m. The thickness from the orebody and its dip as well as the thickness overburden also play a deciding part within the bench height. As pointed out in Coal Trading, the bench height depends up on:

a) Deposit character and geology: selectivity;

b) Production approach: ore/waste ratios, blending needs, no. With working faces, operating/capital charges, etc.;

c) Slope stability considerations;

d) Equipment set / equipment particular optimum geometry.

Bench Slope is decided by the geo-technical circumstances on the overburden and the orebody.

This is also decided by the geo-technical stability on the rocks in the mine, bench height and bench slope. All round pit slope is constantly less than the bench slope.

This really is usually decided based on the space essential for the operation from the equipment on it.

This depends on the operating parameters of the trucks and other hauling equipment used in the mine. It is often wider than the bench width.

The length in the bench depends upon the production rate. A bench will be longer for a higher production rate. Normally, blasting at one bench is done not more than once a week. The extent from the orebody also has a deciding function here.
