摘要
通过尖山铁矿设计实例,提出对新建及改扩建矿山采用无底柱分段崩落法时应重视覆盖层厚度的分析研究,实现有序放矿,为矿山顺利达产提供保障。
It analysis and struction and for achieving was pointed out by Jianshan Iron Mine' s design examples that more attention should be paid to the research on the overburden layer thickness during the process of a mine's new construction, recon- expansion with nopillar sublevel caving to realize ordered ore drawing, which provide guarantee smoothly a mine's design capacity.
