Mine survey
Mine surveying, in the mine construction and mining process, surveying and mapping work for mine planning and design, exploration and construction, production and operation management, and mine scrapping. Its main tasks are:
1 Establish mine site and control network and surveying 1: 500-1: 5000 topographic map and mine map; 2 Conduct construction survey and completion acceptance survey of various ground and underground mines; 3 Perform deformation monitoring of rock and surface movement, The main work content for protecting pillars and safe mining is: to establish the ground control network of the mining area, the mapping of the topographic map of the mining area, the measurement of mine construction, the observation of surface movement settlement and the drawing of ore body geometry. Among them, mine construction survey is the measurement work carried out for the construction of various projects during mine construction and mining, that is, civil engineering survey on the ground, downhole control measurement and construction survey, shaft orientation measurement and shaft lead elevation measurement, shaft Through measurement. During the construction and operation and operation and management stages, it is also necessary to regularly observe the sedimentary observation of rock strata and surface, the settlement observation and displacement observation of various parts of the roadway and the body and its related buildings and auxiliary buildings, and the rehabilitation of the mining area. Measurement services, etc.
2. 3D laser scanner for mine measurement
The use of laser scanners for terrain and mine surveying is currently the world's most advanced measurement technology. Because laser scanners can acquire data at very high resolutions and obtain 3D data, it is easy to generate digital elevation models that are more accurate than other conventional measurement methods. Compared with the traditional GPS+ total station measurement operation mode, the operation efficiency is higher, the advantage is very obvious, and the work intensity of the field personnel is greatly reduced.
