CHINA MINE ENGINEERING

Based on the study of block caving method in inclined ore bodies in some mines at home and abroad, this article uses PCBC software and combines factors such as ore body collapsibility, ore body morphology, induced stress, rock mass structure characteristics, and mining safety to study the undercutting sequence of block caving method in Panjiatian Iron Mine. The research results indicate that PCBC software has practical value in determining the optimal mining height, calculating the mineable amount, determining the undercutting sequence, and preparing production schedule plans, providing reference value for determining the undercutting sequence of block caving method in similar mines.
