在倾斜的层状矿床中,露天坑的极限深度和经济服务期限可能受下盘边坡设计的限彻。边坡的稳定性和下盘边坡的设计又强烈地受工程地质和岩石力学参数的影响。为了评价边坡的性态,深入掌握矿床的构造地质、工程地质和地质构造史是最重要的。这对于又长又高且无台阶的下盘边坡尤其重要。合理的下盘边坡设计需要对提出的边坡几何形状进行检验和计算,采用每一种可能
In sloping stratiform deposits, the ultimate depth and economic service life of open pit may be limited by the slope design of the lower slope. The stability of the slope and the design of the footwall slope are strongly influenced by engineering geology and rock mechanics parameters. In order to evaluate the nature of the slope, it is of paramount importance to master the tectonic geology, engineering geology and geological tectonics history of the deposit. This is especially important for the long, tall, stepless undercut slopes. Reasonable wall slope design needs to be tested and calculated for the proposed slope geometry, using every possible
