Deep mining comes with its own unique complexities, uppermost among these the problem of controlling the flow of water. Water can become problematic in mine engineering through two means; rain water and underground aquifers. Rain water can flow into the access points of the mine shafts and collect inside the tunnels causing damage and deterioration.
Engineering principles can be employed to prevent the rain water from flowing into the mine shafts and can be diverted by a number of means away from the entrances to the mine. This can be done simply by raising the entrance to the mine or lowering the surface area around the tunnel access point. Under ground water aquifers need a slightly different approach. The mine shafts and tunnels may need to be waterproofed against seepage from the water table into the mine shafts.
This can be done by increasing the thickness of the aquifer thereby decreasing the flow of water through the bedrock or soil. The water can also be diverted or re-directed using pipeline technology, canals and channels. A mine engineering expert will be able to identify the best approach to limiting unwanted water in the mine shafts and tunnels and employ these means optimally.
Water is problematic for a number of reasons, mainly due to the destructive nature of the flow can cause. Soil and dirt can become loose due to the flow causing deterioration that can lead to a tunnel collapse. This is a major safety concern for the miners involved in the mining process as well as the production capacity of the mine. Other methods and applications such as struts to strengthen mine tunnels and prevent collapse can also be taken by a mine engineer.
