摘　　要：根据矿体的开采技术条件,提出了可应用于此矿体的3种采矿方法方案,通过AHP和均方差法对3个方案进行综合分析,最终确定方案二为推荐方案,即底盘漏斗中深孔落矿采矿法。对所选的采矿方法进行了试验,通过试验采出4.03万t矿石,损失率25.8%,贫化率5%,取得了比较理想的试验结果,创造了可观的经济效益,为缓倾斜厚矿体采矿提供了可靠的经验。According to orebody mining technical conditions,the three mining methods can be applied to mine the ore body.The AHP method and mean square error method are used to make a comprehensive analysis on three schemes,and then determine the solutions,the chassis funnel deep hole shrinkage mining method is recommended ultimately.The selected mining method is experimented.Through the test produced 40 300 t,ore loss rate is25.8% and dilution rate is 5%.The mining method experiment results create considerable economic benefits and provide experience for gentle-inclined thick orebody mining.
