Key technology and equipment for fully mechanized mining with extra-large shearing height of 10 m in extra-thick coal seam

Meitan xuebao
Fully mechanized mining technology with extra-large shearing height is the optimal technical approach to achieve high-yield, high-efficiency and high-recovery mining for 6−10 m ultra-thick coal seam in Chinese coal mines. Based on the analysis of the current status of fully mechanized mining technology and equipment with extra-large shearing height at ...
