METHOD FOR STOPE-AND-FILL MINING IN SECTIONS

摘要

A method for stope-and-fill mining in sections involves the processes of stoping and filling in layers and in sections, mining and filling the whole mining area from bottom to top. Each batch of ore body being mined is in the shape of prism, adopting 4 accesses: a stoping access (3) at the bottom, a filling access (11) at the top and two refilling accesses (9) on two sides. Each batch of mining mainly involves 3 steps: stoping, filling and tamping. After finishing one batch of mining for ore body, the refilling access (9) is changed into a stoping access (3), and the filling access (11) is changed into a refilling access (9). This mining method is of high efficiency and safety.
