摘要: 玲瓏金礦255主運巷處于復雜的地質環境條件下,構造活動帶巖土體動力穩定性和巖體結構探測與地質超前預報是工程有效治理的前提.依據現場雷達探測分辨率要求,選定250 MHz屏蔽天線探測,找到空區隱患的準確位置和圍巖特征,為255主運巷后期的加固與治理提供了依據.

Abstract: Ground penetrating radar (GPR) surveys were conducted in rock mass structure detection and advanced geological prediction for 255 roadway in Linglong Gold Mine of China. The targets of the GPR surveys were to abtain the near-surface mined-out area features associated with dynamically induced liquefaction and disturbances. The GPR survey results using a 250 MHz antenna at the sites of some examples show that GPR is useful to locate subsurface features in the mined-out area for hazard assessment.
