Research on Adaptability of Full-mechanized Caving Mining with Large Mining-height
2011
Procedia Engineering
In order to solve the safety problem from methane concentration in mining face with high m ining intensity, fullmechanized top-coal caving mining with large mining-height was put forward. In spite of its advantages in controlling methane, its main problems were pointed out. Higher mining height might reduce coal-wall stability and result in coal or roof fall. Top-coal caving difficulty degree might increase with larger top-coal thickness. Numerical simulation software applied, coal-seam
