Investigations on Rockmass Structure Characteristics and Mechanical Mining Efficiency and Economics in the Jinchuan No. 3 Mine With Hard Rock

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Geomechanical characterization is crucial for assessing the feasibility of the mechanical construction method in geotechnical engineering, which is a construction method that neither uses explosives nor involves blasting operations. But for hard rock mines, relying solely on rock strength data is insufficient to estimate the applicability of cantilever
