Excerpt from A Study of Mine Surveying Methods: And Their Applications to Mining Engineering These notes, problems and observations have been compiled in order to present in useful form for the student much that is today scattered among various texts on surveying and much from practical work that is not included in the average series of lectures on mine surveying. The surveying of lode and placer claims has been omitted, as the present methods of conducting such work are very different from practice in underground work, and recent legislation has caused considerable confusion in all mineral surveys. Mine surveying is really one part of mining engineering. The purpose of these notes is to show how mine surveying enters into all the other phases of mining engineering and what methods are best adapted to each kind of work. It is assumed that the student has a good knowledge of the instruments and methods of plane surveying. He should be skillful in handling and adjusting the various instruments. Instruction in the art of adjusting the transit as used in mining work should be given before underground work is attempted Definition. The following definition is included in the introduction to Johnson's "Theory and Practice of Surveying" "Surveying is the art of making such field observations and measurements as are necessary to determine positions, areas, volumes, or movements on the earth's surface. The field operations employed to accomplish any of these ends constitute a survey. Accompanying such survey there is usually the field record, the computation, and the final maps, plats, profiles, areas, or volumes. The art of making all these belongs, therefore, to the subject of surveying." Mine surveying is generally defined as the art of making such measurements as may be necessary (a) to determine the location and extent of bodies of coal, ore, etc., (b) to determine the relative positions of points in the mine with regard to each other or to points on the surface.
