摘要
针对湖北银矿矿体倾角大 ( 5 7°～ 80°) ,厚度薄 ( 1～ 3.8m)的特点 ,在确定采用浅孔留矿法开采的基础上 ,通过生产实践 ,试验了铁漏斗、振动放矿、无底柱等不同放矿结构的技术经济参数与应用条件 ,并在生产中灵活运用 。
In view of the characteristics of large inclination (57°～ 80°) and small thickness (1～ 38 m) of the orebody in Hubei Silve Mine, the technical and economical parameters and conditions of the application of various ore drawing structures such as iron funnel,vibration and nonpillar drawing methods were investigated through tests in short hole schrinkage mining. The flexible application of the drawing methods achieved very good results.
