摘　　要：为解决某银多金属矿复杂多变的急倾斜薄矿体回采能力低的难题，在矿山现有削壁充填采矿法的基础上，引入平底结构浅孔留矿法。根据矿体厚度变化情况选择不同的采矿方法，在实践中取得了较好的技术经济效益，同时，也为国内其它类似开采技术条件的矿体提供了借鉴。In order to solve the low mining capactity of the complex steeply inclined thin ore body in a silver polymetallic mine, we introduce a short-hole shrinkage stoping method with flat-bottom structure based on the existing waste lifting stoping method. According to the change of thickness of the ore body, we chose different mining methods, the short-hole shrinkage stoping method with flat-bottom structure or the waste lifting stoping method, and the technical and economic benefits are obtained in practice. At the same time, the scheme provides reference for other ore body mining with similar conditions in China.
