In the training of mining engineers, it is necessary to master the means of developing projections with numerical marks that are most rational when depicting surfaces in which the height dimensions are much smaller than the horizontal ones. The absence of the usual coordinate system, namely the frontal and profile planes of projections, makes some adjustments to the methodology of depicting geometric elements and leads to the need to use specific notations and methods for solving geometric problems. The paper considers the peculiarities of solving a typical problem of descriptive geometry on a drawing with numerical markings. Also, the basic terms and concepts used in the development of surveying drawings are given.
