In connection with the plan and pace of development of mining and geological exploration, the survey department is currently facing a number of important tasks, namely: A. Technical reconstruction and technical revolution 1) Elimination of technical backwardness (introduction of a unified coordinate system, guarantees against gross errors, introduction of the “Z” coordinate, etc. 2) Increasing survey accuracy (accuracy of measuring angles, lengths, orientation, etc. 3) Introduction of new survey methods and business techniques (precise tacheometry in the mine, photomechanical reproduction of plans and other documents, the use of photogrammetry to survey open-pit works, etc. 4) Adaptation of surveying technology to the new pace of mining (consoles, hanging theodolites, new orientation methods. B. Adaptation of mine surveying to serve planned construction (see article). B. Regarding general and organizational issues (see article).
