充填体下水平矿柱开采技术研究

Mining technology research on horizontal pillar under backfill

充填体下水平矿柱应力较为集中,其开采顺序及采矿方法对控制水平矿柱以及矿区稳定有重要作用。开展水平矿柱开采顺序研究,采用水平矿柱与矿柱协同开采顺序。对水平矿柱可行的采矿方法进行分析,选用安全高效的采矿方法。通过制定合理的开采顺序以及采矿方法保证水平矿柱回采过程稳定,最大程度回收水平矿柱资源。

Stress on horizontal pillar under backfill is more concentrated, the mining sequence and mining methods play an important role to control the stablity of horizontal pillar and mining area. To study the horizontal pillar mining sequence, adopt the pillar and horizontal pillar synergetic mining sequence. Analyzing feasible horizontal pillar mining method, select the safe and efficient mining method. Through adopting the rational mining sequence and mining methods to ensure the stbablity in the process of horizontal pillar mining, exploit the horizontal pillar resources in the maximum degree.
