SURVEYING AND MAPPING OF UNDERGROUND MINES

A mine surveyor provides services from early design and project implementation throughout a mine`s life to closure. Surveyors deal in spatially referenced information and measure angles and distances to document the positions of mining features and boundaries, and present the information in the form of mine maps.In an underground mine, surveys are typically performed in dark, confined and often wet spaces, and special equipment and methods have had to be developed to comply with underground safety regulations. Deep mine surveys must be performed in 3 D and underground and surface surveys must be correlated. Underground surveys are performed at different levels of precision
