摘要
南京冶山铁矿经过 30多年的开采 ,已形成较大的连续空区。为了防止空区大面积冒落引发的地质灾害 ,采用 3维数值法对采空区的稳定性进行计算分析 ,并对下部矿体安全开采今后拟采取的的安全技术措施提出一些建议和看法。
Large continuous mined area has formed in Nanjing Yeshan Iron Mine which has undergone over thirty-year minning.To prevent the geological disaster caused by large caving in mined area,three-dimensional numerical method is used in the calculation and analysis of the stability of mined area.Some suggestions and opinions relating to the technical measures to be taken in the future for the safe mining of the orebody in the lower part are given.
