摘要
为制定遂昌金矿某矿体的安全高效开采方案,需要首先确定矿岩的稳定性情况。为此在井下三个中段开展取样试验、构造调查和声波测试工作,利用DIPS软件统计分析调查结果得出岩体的优势节理面,结合岩石和岩体的声波测试数据计算完整性系数,并通过BQ系统综合评判工程岩体质量,评定井下工程岩体的级别,评述开挖后岩体的自稳能力,为矿山安全、合理、高效地开展采矿作业提供技术支撑。
In order to safely and efficiently exploit the ore-bodies in Suiehang Gold Mine, the stability of the ore-bodies should be identified firstly. The researches of sampling and experiments, structure investigation and acoustic tests have been done in three stages. The results of structure investigation are statistically analyzed with DIPS software and the superior joint group of the rock-mass is obtained. According to combining and analyzing the acoustic testing datum of the rock and rock-mass, the completeness coefficients are calculated. Then the quality of underground engineering rockmass is assessed with BQ system. The classification is given and the self-steady ability after excavating is judged. All of these researches can provide technical support for safe, reasonable and efficient mining.
