During open-pit bench blasting, the movement trajectory of rock in the bench area is an important factor affecting the accurate mining of open-pit mines, especially for unevenly mineralized ore bodies. In order to solve the difficult problem that the internal movement trajectory of rock during bench blasting in the Wushan Cu-Mo mine is not clear, a tracking algorithm with signal markers was used on bench blasting tests at the Wushan Cu-Mo mine in Manzhouli. Through on-site installation, positioning, monitoring and data analysis of intelligent beacons, the research results showed that: the first row of beacons had a long motion time and fast movement with an average speed of 5.89.8 m/s. The movement distance was between 18.4 m and 29.4 m. Due to constraints and obstruction of the rock mass in the front section of the bench, the motion time, movement speed and distance of the#2 monitoring beacon were significantly reduced, with an average speed of 1.8~4.8 m/s and a movement distance of 5.3~14.2 m. The movement distance and time of the#3 blast hole beacon was the smallest, and the inclination angle of the#3-3 beacon reached about 25°. The inclination angles of#6-1, #6-2 and#6-3 beacons were relatively gentle at about 2°~8°. From the depth perspective, the shallow beacons move forward horizontally during the forward rush period, and there was a significant downward trend in the latter half. The vertical motion distance of the deep beacons was significantly smaller than that of the shallow beacons.

在露天矿台阶爆破时,台阶区域内的岩石移动轨迹是露天矿实现精准采矿的重要影响因素,尤其针对矿化不均匀的矿体。针对乌山铜钼矿台阶爆破过程中内部岩石移动轨迹尚不明确的难点问题,将通过采用信号标志物的跟踪算法,并依托满洲里乌山铜钼矿开展了现场台阶爆破测试。通过现场智能信标安装、定位、监测和数据分析,研究结果表明:第一排信标运动时间长,移动速度快,平均速度达到5.8~9.8 m/s,运动距离在18.4~29.4 m;由于受到台阶前段岩体的约束和阻碍,2#监测信标的运动时间、飞行速度与移动距离明显下降,平均速度为1.8~4.8 m/s,运动距离为5.3~14.2 m;3#爆破孔信标移动距离和移动时间最小,3-3号信标斜向下俯冲角度达到25°左右,6-1、6-2、6-3号信标斜向下俯冲角度较为平缓2°~8°左右。从深度上来看,浅部信标在前冲的这段时间内,前半段水平向前移动,后半段有明显的下降趋势,深部信标的垂直运动距离明显小于浅部信标。
