Description

Technical Field

[0001] This utility model relates to the field of mine detection technology, specifically a mine pressure detection device. Background Technology

[0002] A mine pressure detection device is used to measure the pressure of rock strata during mine operations. As resource utilization increases, mining operations become increasingly important, making mine pressure detection devices equally crucial.

[0003] In the existing technology, existing mine pressure detection devices cannot measure minute displacements, making it difficult to install the roof plate on the rock strata at the corresponding angle. The anti-slip performance is also imperfect. In addition, the distance between rock strata in mines is mostly unequal, and the limited extension height of pressure detection equipment on the market restricts detection. Utility Model Content
