【摘要】：在无底柱分段崩落法工业现场条件下测定的放出体形态,比传统实验室试验和数值模拟测定的放出体形态更加符合现场实际,但该测定方法的难点在于低劳动强度、高回收效率的标志物及其监测系统的开发。为解决该难题,首先基于RFID无线射频识别技术,开发制备了抗爆破冲击和可高效识别的标志物。针对该标志物采用的EM9202芯片,研发并建立了标志物监测系统,该系统可准确识别标志物出现的时间及编号。最后在梅山铁矿-306 m水平4-5LS1进路第10排进行试验应用。结果表明:标志物回收效果理想,尤其对于流动性较好的3个中间测试孔,标志物的回收率达到了87%;同时监测系统运行状态良好,测试数据准确。
[Abstract]:Compared with the traditional laboratory test and numerical simulation method, the shape of the ejector measured by sublevel caving method without bottom pillar in the industrial field is more in line with the field reality, but the difficulty of this method lies in the low labor intensity.Development of high recovery efficiency marker and its monitoring system.In order to solve this problem, first of all, based on RFID radio frequency identification technology, the anti-blast impact and high-efficiency identification markers are developed and prepared.According to the EM9202 chip, a marker monitoring system is developed and established. The system can accurately identify the time and number of the marker.Finally, the test was carried out in the 10th row of the 4-5LS1 route at -306m level in Meishan Iron Mine.The results show that the recovery of markers is ideal, especially for the 3 intermediate test holes with good fluidity, and the recovery rate of markers reaches 87%, and the monitoring system is in good condition and the test data are accurate.
