摘要
利用超声波检测技术,对大理石矿岩石物理力学参数和围岩完整性进行测定及测试,指出了该矿的岩石具有很高强度,对该矿上水平矿柱的稳定性进行评价具有重要意义;同时,分析了该大理石矿的3种岩石的分布情况,为开采大理石提供了重要依据。
Using ultrasonic detection technology, we determine and test physical parameters and rock integrality of marble rock, point out rock take on high intensity which is great significance for the mine ore-evaluation of the stability on the upper level; at the same time, analysis of the distribution of the three marble rocks, provide an important basis for the extraction of marble.
