随着无轨采矿的推广,上向分层充填法实现了全面机械化,现在通称为机械化分层充填采矿法(MC&F)。此外,还出现了下列变型方案,进一步扩大了这一方法的应用范围:1.一步骤回采的点柱(post pillar)分层充填法;2.用于急倾斜薄矿脉的顺路斜坡道分层充填法;3.长锚索预护顶分层充填法;4.一步骤连续回采的分条分层充填法; 5.适
With the introduction of trackless mining, the fully mechanized approach to tiered filling is now commonly known as Mechanized Stratified Filling (MC & F). In addition, the following variants have been introduced to further expand the scope of application of this method: 1. Post pillar stratification filling; 2. Stratified ramp ramp for steeply dipping thin veins; Filling method; 3. Long anchor cable prefabricated top filling method; 4. One-step continuous mining sub-strip filling method;
