摘　　要：安全顶板厚度是顶板达到临界破坏状态时对应的厚度,采用二分法优化理论,对冶山铁矿下部盲矿体开采留设不同厚度尺寸的顶柱进行了模拟,得到了较为精确的安全顶板厚度,在保证矿体安全回采的同时最大限度地回收了矿产资源。Safety thickness of roof is the corresponding thickness when the roof reach the critical failure state. Simulation analysis was done on shore which setting different thickness of blind ore body exploitation of bottom Yeshan iron ore by dichotomy optimization theory, much accurate safety thickness of roof was obtained, and it furthest recovered the mineral resources and assure the safety stoping of orebody at the same time.

关 键 词：安全顶板厚度 临界破坏状态 二分法优化
