"How the Bench Height is decided for OC mine?"

Question

Accepted Answer

The bench height for an open-cast mine is determined based on factors such as the type of material being mined, equipment used, safety considerations, and economic factors.

Bench height refers to the vertical distance between each level or bench in an open-cast mine.
It is determined by considering the type of material being mined. For example, softer materials may require smaller bench heights to prevent slope instability.
The equipment used in mining operations also influences bench height. Larger equipment may require higher bench heights to accommodate their size and reach.
Safety considerations play a crucial role in determining bench height. Adequate bench height ensures the stability of slopes and reduces the risk of accidents.
Economic factors, such as the cost of mining and extraction, also impact bench height decisions. Higher bench heights may allow for more efficient extraction and lower costs.
Geological conditions, environmental regulations, and local mining practices also influence bench height determination.
