摘    要:自然崩落法采矿过程中,实时掌握顶板崩落规律尤为关键。本文利用空孔监测技术,对普朗铜矿顶板崩落的动态变化情况进行监测。根据监测数据,实时获得崩落面和存窿面之间高度变化,计算出顶板平均日崩落速度,并依据设计参数动态调整底部结构的放矿计划。空孔监测技术在该矿实时监测顶板崩落规律中得到了很好的应用,具有较好的推广应用价值。

关 键 词:自然崩落法  空孔监测  顶板冒落  崩落速度

Abstract:In the process of block caving mining, it is very important to grasp the law of roof falling in real time. In this paper, the open holes monitoring technology is used to monitor the dynamic change of roof falling of Pulang copper mine. According to the monitoring data, mastering the height variation between the caving surface and the storage surface in real time, obtaining the average daily caving velocity of the roof falling, and dynamically adjusting the drawing program of the bottom structure based on the design parameters. Open holes monitoring technology has been well applied in the law of roof falling in the real time monitoring of the mine, and has good value for extension and application.
Keywords:block caving method  open holes monitoring  roof falling  caving velocity
