针对传统CSMR法没有考虑露采矿山边坡出露频率快、存在周期长和边坡高度差异大对岩体质量等级的影响,引入时间影响系数?,修正不连续面与坡面倾角间关系调整参数F3和坡高修正系数?,提出改进CSMR法,对一般露采矿山的不同高度边坡岩体进行质量分级,提高其分级适用性。边坡实例分析表明,改进CSMR法比传统质量分级SMR法和CSMR法更加符合工程实际,运用改进CSMR法对露采矿山边坡岩体质量分级更加合理。
In view of the fact that the traditional CSMR method does not consider the influence of the frequency of dewatered mining slope on the quality level of rock mass with the difference of cycle length and slope height, the time influence coefficient is introduced, and the relationship between discontinuities and slope inclination is adjusted Parameter F3 and slope height correction coefficient, the improved CSMR method is put forward to classify the quality of rock mass at different heights in general open pit mines and to improve their grading applicability. The case study of slope shows that the improved CSMR method is more in line with the engineering practice than the traditional mass fractionation SMR method and CSMR method, and the improved CSMR method is more reasonable for slope rock mass quality classification.
