七宝山硫铁矿是一个以硫、铜为主的多元素矿床。矿体开采技术条件复杂,应用现行采矿方法有一定弊端,较突出的问题是采矿损失大,矿山效益不理想。笔者认为,下盘出矿的矿块崩落法方案较适宜该矿的Ⅰ-1矿体的开采技术条件,现提出供参考。 一、现行采矿方法的主要弊端 设计开采范围内的老虎口矿段有大小矿体48个,主要开采对象是Ⅰ-1号矿体,它占整个矿段总储量的71％。矿体产状变化大,倾角0～75°,厚0.35～33.4米,厚大区域产
Qibao Shan Pyrite is a sulfur, copper-based multi-element deposit. The technical conditions of orebody mining are complex. There are some drawbacks in applying the current mining methods. The more prominent problems are the large mining losses and the ineffectiveness of mines. The author believes that the next plate out of ore mining program is more suitable ore mining Ⅰ-1 ore mining conditions, are presented for reference. First, the main drawbacks of the current mining methods Design within the scope of the mining section of the Tiger mouth mine has 48 ore bodies, the main mining object is No. I-1 ore body, which accounts for 71% of the total ore reserves. Large changes in ore body shape, dip 0 ~ 75 °, thickness 0.35 ~ 33.4 meters, thick area production
