摘要
介绍了在鹤庆县锰矿缓倾斜厚矿体中,试验成功的人工柱锚杆房柱采矿法。其特点是,采用人工柱替代矿石柱,锚杆网支护不稳固顶板,大幅度地提高了矿石回采率。经过11个矿房的试验回采,取得了较好的经济效益。
It described the suscessing test with pillar mettled which have applied manual pillar at gentel dip thick orebody in Heging Manganese Mine.The salient features is used manual pillar instead of ore pillar belt to suppout unstable roof,and increases the recove.This method was performs in 11 roof's recovery test,and obtains good economic effect.
