金川露天矿高边坡的反射地震CT探测研究

SEISMIC REFLECTION STUDY ON HIGH SLOPE ROCKMASS IN JINCHUAN OPENCUT MINE BY CT METHOD

摘要: 高边坡的岩体结构和稳定性研究是工程地质研究的一个重要课题。本次探测使用高分辨率数字地震仪和反射地震CT方法,对金川露天矿高边坡的岩体结构进行了深入细致的探测与研究,清楚地揭示了边坡岩体中优势结构面的产状和组合关系,以及边坡表层松动带厚度分布,未发现顺坡软弱岩层。

Abstract: The structure and stablity of high slope rockmass are important problems for engineerin geology studies. Using the high resolution seismograph and seismic tomograpy of reflections, the high slope rockmass of Jinchuan opencut mine is studied in detail. The result reveals clearly the thickness of the surface loose layer predominant structural faces, and joint weak interface in the rockmass. No weak layer down slope is found.
