摘　　要：红花沟金矿15-6号矿体属急倾斜中厚矿体,且矿岩稳定性较差,采用削壁充填采矿法回采易导致采场作业安全条件欠佳且极易造成大量的采矿损失贫化。根据红花沟金矿15-6号矿体的开采技术条件,开展了上向水平分层分步充填采矿法试验研究,其实质是基于上向水平分层干式充填采矿法,将采场分步骤回采,控制采场跨度,确保采场顶板稳定与生产安全。该方案很好地解决了厚度为8~10 m的中厚矿体开采问题,有利于矿山完成生产任务并提高经济效益。The No.15-6 ore body in Honghuagou Gold Mine belongs to steeply inclined medium-thick ore body that has poor ore rock stability.So resue-and-fill mining method can easily lead to poor safe operation conditions in the stope and great mining loss and dilution.According to the mining technical conditions of No.15-6 ore body in Honghuagou Gold Mine,experimental study on upward horizontal slicing step-and-fill mining method was carried out.The method is basically based upon upward horizontal slicing dry filling mining method,mines the stope in steps,controls the stope span,and ensures the stability of the stope roof and the safe operation.The scheme effectively solves the challenges to mine the ore bodies with the thickness of 8-10 m,and is beneficial to meeting the production goal and increasing economic profits.
