What is the minimum safety distance for mine workings driven under accumulation of running water on unfractured rock?

The minimum safety distance for mine workings driven under accumulation of running water on unfractured rock is set at 25 meters. This distance is essential to mitigate the risk of flood hazards and ensure that water does not undermine the structural integrity of the mine workings. The 25-meter guideline provides a buffer that can safeguard miners and equipment from unexpected water movement or pressure that could lead to collapses or other dangerous occurrences.

Setting this distance is based on hydrological studies and geotechnical assessments that have demonstrated that maintaining a clear distance from potential sources of water is critical in preserving safe mining operations. Proper adherence to this safety measure helps to minimize accidents related to flooding and enhances the overall safety of the mining environment, ensuring that the structural stability of the surrounding rock can support the mine workings effectively without the risk of water infiltration causing erosion or subsidence.
