Engineers use rock mechanics to design support systems (like rock bolts or shotcrete) that prevent tunnels from collapsing under the weight of the mountain above.
This involves measuring how rock deforms under pressure. Because rocks are often brittle, rock mechanics calculates "yield points"—the exact moment a rock will crack or shatter. Fundamentals and Applications of Rock Mechanics
Understanding rock mechanics allows engineers to intentionally crack rock layers to release oil or gas. Engineers use rock mechanics to design support systems
