Description

Technical Field

[0001] The utility model belongs to the technical field of underground mine production, and in particular relates to a pit mine surveying and line drawing auxiliary device. Background Art

[0002] Mine surveying is an indispensable part of mine construction and mining. Its main tasks involve many aspects, including establishing a ground control network in the mining area, mapping topographic maps and mine maps, and conducting construction surveys and completion acceptance surveys for various projects. Mine surveying is of great significance for guiding mine construction and production, ensuring safe production in mines, and improving resource utilization efficiency. When surveying a mine, professionals are required to draw the center line and waist line, where the center line is a straight line and the waist line is composed of a straight line and an inverted triangle. The center line and waist line of the pit mining tunnel are the most intuitive signs in the mine construction and mining process, which are directly related to the quality of engineering construction, and standardized drawing is the key. At present, the center line and waist line used in underground mine production are hand-painted by spray paint, which has problems such as non-straight lines and a small amount of deviation, which has a certain impact on the construction.
