摘　　要：局部充填分段采矿法,是一种创新采矿法。它的特点是利用采空槽扩帮来形成分段平巷,扩帮的废石作为充填料,不需运出。采矿工作是在分段平巷中进行,所以工作安全。这个方法有许多优点:采收率高,贫化率低等等。它与留矿法比较,具有很大的经济效果。特别适合于钨、锡、金薄脉型矿床,倾角在30°以上。Partial-filliing-and-sublevei-method is a new mining method.It is characterized by the process that the sublevel is formed by expanding the mined trough, and the waste is used as fillings without drawing out. The mining work is under way in the sublevel,so that safety is assured.This method has many advantages, such as:highextraction, low dilution etc. As compared with shrinkage, partial filling and sublevel method has great economic efficiency, especially suitable for tungsten, tin and gold depo-site with their occurence in the form of narrow vein and dipping above 30°.
