针对缓倾斜破碎中厚矿体开采条件,大尹格庄金矿改进原有上向水平分层充填采矿法,试验应用了高机械化、高安全性、高生产效率的盘区机械化上向水平分层充填采矿法,详细介绍了该采矿方法回采工艺过程.生产实践表明,改进后的采矿方法适合于缓倾斜破碎中厚矿体的开采,取得了良好的技术经济效果,可为同类矿山提供借鉴.
According to the development conditions of moderately dipping fractured medium-thick ore body,Dayin'gezhuang Gold Mine renovates the previously used upward horizontal slicing method by the highly mechanized,safer and more efficient mechanized upward horizontal slicing tailings filling method.The paper in detail describes the extraction process of the mining method.Practice shows that the renovated method is suitable to the development of moderately dipping fractured medium-thick ore body.The method achieves satisfactory technical index and is worth referring to by similar mines.
