Description

Technical Field

The disclosure relates to the technical field of deep stratum detection, in particular to a method for acquiring and predicting joint information in deep metal ore granite rock.

Background

Under the action of high-stress and high-water pressure geological structures, the deep stratum is easy to exceed the bearing capacity of the rock and is subjected to plastic deformation, so that joints and cracks with various angles exist in the deep stratum. The through joint angle is particularly dangerous, water burst and water burst accidents are easy to occur in the deep engineering construction process, and a large number of researches and engineering practices prove that the prevention and the control of water damage in the deep mine construction are particularly important, so that the occurrence state and the importance of stratum joints and cracks in the deep engineering area construction area are ascertained.
