Description

Technical Field

[0001] The utility model relates to the technical field of coal mine measurement equipment, in particular to a portable coal mine geological measurement device. Background Art

[0002] Coal mine underground measurement is an important part of achieving safe production during the production and construction of mines. It is an important and rigorous technical work and an important means for coal mines to complete production technology management and achieve safe production in coal mines. Underground measurement is carried out in the tunnel. When using the existing coal mine geological measurement bracket, due to the uneven ground of the mine tunnel and the distribution of gravel, the existing measurement bracket is difficult to place in a balanced manner.
