Problems solved by technology

Conventional two-dimensional fracture network models are usually realized in the form of two-dimensional data, but the scope covered by two-dimensional data has certain limitations, and the acquisition of two-dimensional data itself has certain limitations. After the data generates a two-dimensional profile, the reliability of the real rock mass that can be represented is greatly reduced
