摘要
贞丰簸箕田金矿矿体赋存条件复杂,岩体及顶底板岩石稳定性差。为达到相应的安全技术及技术经济指标标准,采用层次分析法和模糊数学法确定最优的采矿方法,得出了上向进路充填采矿法、上向水平分层充填采矿法、下向分层充填采矿法3种采矿方法的优劣顺序。并用FLAC3D数值模拟软件分别进行了3种采矿法的模拟,最终优选出上向进路充填采矿法为簸箕田金矿的开采方法,并取得了良好的实践效果。
The occurrence conditions of gold ore are complex in ZhenfengBojitian Mine,and stability of rock mass roof and floor is poor.In order to achieve the corresponding safety technology and technical and economic index standards,using AHP and fuzzy mathematics to determine the optimal mining method,theobtainedsequence of the three mining methods include upward horizontal cut and fill mining method,upward drift cut and fill mining method,downward cut and fill mining method.In addition,the three kinds of mining methods are simulated by FLAC3D numerical simulation software,and finally the upward drift cut and fill mining method is selected as the Bojitian gold mining method.Thus,good practice effects have been achieved.
