In the process of block caving mining,it is especially crucial to grasp the roof caving law in real time.In this paper,the open holes monitoring technology is used to monitor the dynamic change of roof caving in Pulang copper mine.According to the monitoring data,the real-time height variation between the caving surface and the storage surface is obtained,and the average daily caving speed of the roof is calculated.According to the design parameters,the drawing plan of the bottom structure is adjusted dynamically.Open holes monitoring technology has been well applied in the roof caving law in the real time monitoring of the mine,and has better value of extension and application.
