摘要
覆盖层厚度的确定是崩落法开采的关键,针对大红山铁矿开采的实际情况,分别从满足井下开采采矿工艺、开采安全方面,采用理论计算及数值模拟分析,得出大红山铁矿崩落法开采的覆盖层合理厚度。
Obtaining the thickness value of the cover rock is the key factor of the caving method. In view of the actual situation of the mining in Dahongshan iron mine, The thickness value of cover rock of caving method in Dahongshan iron mine is acquired by adopting the theoretical caculation and numerical simulation method from the perspective of the mining technology of underground mining and mining safety respectively.
