Theory teaching
Introduction. Basics of engineering graphics, importance and application in mining. Drawing formats, header, component, legend, size. Basic characteristics of graphic primitives - point, lines, polygon. Technical letter. Projections, types and application of projections in the representation of mining objects. Types and way of listing, application of position numbers. Coordinate systems in the plane and space. National Coordinate Systems, Gauss-Kriger Projection, Universal Transversal Mercator Projection. Engineering graphics in mining. Definitions, application, content and interpretation of topographic and mining maps and plans. Contents of drawings of buildings, machinery and power plants. Definitions, method of making and applying cross sections, profiles, schemes and diagrams, 3D models. Methods of displaying mining facilities and deposits of mineral raw materials. Wells, ore bodies, floors of surface mine and landfill, underground mining premises. Roads, crops, embankments, platforms, ramps, channels. Mechanisms, devices and equipment Infrastructure facilities. Mining symbols and labels. Determination of the spatial position and geometry of mining objects using graphoanalytic methods. Determine the coordinates of the points on the plan, the length, the directional and the horizontal angles, the height of the points, the surface of the figures of the correct and irregular shapes, the body volume of the correct and irregular shapes. Examples of the application of the graphoanalytic method. Digital engineering graphics. Application of computer technology in engineering graphics.
