【摘要】：由于残矿空间形态的复杂性,传统的剖切作图方法难以直观全面地掌握该类型矿体形态,进而难以精确指导采切工程的设计,而SURPAC软件采用三维建模方法,能很好地解决这一难题.以西石门铁矿堑沟底部结构诱导冒落法开采残矿为背景,采用SURPAC软件对堑沟内矿石量、金属量、品位等指标进行计算,将堑沟巷道所在的水平和垂直位置作为优化对象,经过对临界冒落跨度和现场工程技术条件的分析,得出堑沟巷道在两个方向上可布置的范围.依据该范围,设计了正交试验方案.以回采金属量和平均品位作为考核指标,对正交试验结果进行极差和方差分析,得出最优的堑沟巷道空间位置:堑沟巷道间距24 m,位于118 m水平.通过现场实施,取得理想的试验效果,实现了残矿的精细化开采.
[Abstract]:Because of the complexity of the residual space form, it is difficult for the traditional cutting mapping method to grasp the ore body shape directly and comprehensively, and then to guide the design of mining and cutting engineering accurately. The SURPAC software can solve this problem by using 3D modeling method, which is based on the mining residual ore by the structure induced caving method at the bottom of the trench in Xishimen Iron Mine. The SURPAC software is used to calculate the ore quantity, metal quantity and grade in the trench, and the horizontal and vertical position of the trench roadway is taken as the optimization object. Through the analysis of critical caving span and site engineering technical conditions, the range of cutting ditch roadway can be arranged in two directions, according to this range. The orthogonal test scheme is designed. Taking the metal quantity and average grade of mining as the evaluation index, the range difference and variance analysis of the orthogonal test results are carried out, and the optimal space position of the cut trench roadway is obtained: the cutting ditch roadway spacing is 24 m. It is located at 118m level. Through the field implementation, the ideal test effect is obtained, and the fine mining of residual ore is realized.

【正文快照】： 我国金属矿山经过多年的开采,受制于当时的开采技术、民采破坏、经济不合理等因素,形成了大量的残留矿体(残矿),这些矿体一般具有开采条件恶劣和形态复杂的特点.现有常规采矿方法均是在完整矿体条件下进行开采,而对于复杂多空区破坏型残矿则不能很好适应,使其开采存在较大的难
