Y-shaped top floor type pillar stopping method suitable for scraper ore removal

The invention discloses a Y-shaped top floor type pillar stopping method suitable for scraper ore removal, which is good in safety, high in resource recovery rate, simple in stopping process flow and good in effect. Compared with trackless equipment ore removal, the electric rake equipment ore removal process has the advantages that the mining work amount is small, the input cost is low, and the working environment is improved; mining projects are all arranged on the periphery of the ore body, the stopping operation safety is high, the dilution rate is low, and the mining technological process is simple. Compared with a regular pillar top cemented filling body, the Y-shaped top original pillar is good in stability, good in stopping effect and high in recovery rate, and economic benefits of mine enterprises are increased. 本发明公开了一种安全性好、资源回收率高、回采工艺流程简单、效果好的适用于电耙出矿的"Y"型顶部楼板式矿柱回采方法。本发明采用电耙设备出矿工艺，相比于无轨设备出矿，采掘工程量小，投入成本少，改善了作业环境；采掘工程均布置在矿体外围，回采作业安全性高，贫化率低，采矿工艺流程简单；"Y"型顶部原生矿柱相比于规则矿柱顶部胶结充填体，稳定性好，回采效果好，回收率高，增加矿山企业经济效益。
