凿岩峒室的稳定性是VCR采矿法安全的重要保障。本文介绍了凡口矿应用超声监测技术在用VCR法回采矿柱的条件下,对因爆破和已采采场所引起峒室围岩的性态变化进行了监测与分析。
The stability of the rock drilling chamber is an important guarantee for the safety of the VCR mining method. In this paper, the application of ultrasonic monitoring technique in Vankou Mine is introduced to monitor and analyze the change of the rock mass in the surrounding rock caused by blasting and mining in the condition of using VCR method to recover the mining pillar.
