摘要
针对赋存条件复杂的缓倾斜极薄矿脉回采难题，开发了单采矿石形成“ Ｔ”字形采空区，并以低矮的全粒级废石胶结条柱支撑顶板岩层，实现无矿石矿柱连续回采的新技术。
To counter the difficult problem of mining gentle dip and extra narrow vein ocurred in complicated conditions,the “T” shaped mined out area caused by only ore mining was developed with its roof stratum supported by low and short columns which were made from unsized waste rocks through cementation,thus the new technique of ore stoping in succession without ore pillar came into being
