摘要
露天采场内矿（岩）石溜井，随开采台阶下降须进行降段．文中评述了“空井法”、“满井法”的降段条件，介绍了防止溜井堵塞跑矿的措施。
The orepasses in the open pits need to be lowered step-by-step as the mining benches advanced downwards. The coniditions of orcpass step-ping-down with the“orepass void” method and“orepass full”method and the measures for preventing the orepass plugging and ore slip-flow were described.
