摘要
采用塑性理论分析锡矿山北矿145采顶板冒落机理,其结果与现场观察及实测资料比较吻合。说明在该矿区现有条件下,所用的分析方法是合理的。
In the paper,an analysis of the collapse No.145 workplace roof in the North Mine of Xikuangshan is made according to the plasticity theory.The results tally with what are determined in practice.Therefore this method is a feasible reference to later similar mines.
