Underground Mining Methods and Equipment
Longwall mining is used in horizontal, tabular deposits (mainly coal), while the others have applications in inclined or vertical, massive deposits, a lmost exclusively metallic or nonmetallic. Because the exploitation openings are intentionally destroyed in the progress of mining, the caving class is truly unique. Rock mechanics principles are applied to induce caving rather than to prevent ...

Longwall Mining Method and Design
Longwall mines produce more than 30 pct of all underground coal, up from 5 pct just 15 years ago. The continued growth of longwall mining without appropriate multiple-seam planning may increase the cost and risk of mining. Optimization of the mine design factors is arguably the primary means for controlling interactions between operations.
