What is the purpose of a control survey in mining?

The purpose of a control survey in mining is to ensure accuracy in mine mapping. This process is crucial as it involves establishing precise reference points within the mine to create a reliable framework from which all other measurements can be made. Accurate mine mapping is essential for various operational aspects, including mining safety, resource estimation, and planning of future mining activities.

Control surveys help to maintain a clear and accurate understanding of the mine's layouts, such as the location of tunnels, shafts, and ore bodies, which is fundamental in preventing accidents and ensuring efficient extraction of minerals. This accuracy ultimately leads to better decision-making regarding mining methods and resource management.
