Latest Patents

Chang Zhou holds a patent for an "Evaluation method of ductility of grouted rock mass for advanced renovation of water-sand mixture inrush area." This patent outlines a comprehensive evaluation method that includes several key steps. First, it involves acquiring a spatial distribution law of cracks in overlying strata and establishing both a three-dimensional geological model and a grouted rock mass unit geological model. The method further includes calculating the rock mass quality standard of the target rock strata, performing compression tests on multiple groups of grouted consolidated bodies, and calculating an average value of strain softening indexes. Additionally, it selects multiple groups of grouted target rock strata to calculate an average value of unstable fracture ductility. Finally, the method acquires a permeability strength of the grouted rock mass and calculates and grades an evaluation index of ductility.
