摘要
为了确定哈尔乌素露天煤矿与黑岱沟露天煤矿在同方向推进过程中合理的追踪距离,运用数学模型进行了计算,得出各年度两矿交叉位置互不影响的最小追踪开采距离,并与两矿现推进进度推算出的追踪开采距离相对比,得出相互影响的年份。根据计算结果,为了保持两矿追踪距离的合理性,可将两矿间压帮高度降低到1 100 m,不仅使该水平下部的台阶数目减少,还能增加两矿交叉位置的宽度,减少两矿间相互影响程度,对指导两矿开采计划的编制具有重要指导作用。
To determine the reasonable track distance of same advancing direction for Harwusu Open-pit Coal Mine and Heidaigou Open-pit Coal Mine,mathematical model was used to calculate the reasonable track distance,the minimum tracing mining distance of these two large open-pit mines were obtained,in this distances,the two mines do not influences each other in the overlapping regions. The track distance was also calculated by using the recent advancing process of the two mines,which was compared with the obtained min-imum tracing mining distance,and the time in which the two mines influences each other was also achieved. According to the calculation results,to ensure the rationality of tracing mining distance for these two mines,the dumping covering height can be reduced to 1 100 m,not only has reduced the number of lower steps on this level, but also can increase the width of the overlapping regions, reduce the degree of mutual influence between the two mines,all this can have great guiding significance for the mining design of the two mines.
