Question 8
Mention four problems on water in mining operations
This question is popular, hence, the candidates performed fairly. The question requested the candidates to give the following points:
Problems of water in mining operations
- Water pressure reduces the stability of the slope in open pits.
- Induces sliding of materials in the slope in open pits.
- Increased weight of the unit rock thus higher rates for transportation.
- Freezing water can block drainage paths
- Erosion can cause instability and silting up of drainage systems
- Increased operating costs from discharge of water for equipment and blasting costs.
- Disrupts operations
- Reduces productivity
- Causes inefficient blasting operations
- Reduces slope stability in open pits.
