以国内某排土场堆积散体为研究对象,采用筛分法、块度直接量测法和摄影-图像分析法相结合的测量方法对该排土场岩石块度分布规律进行了测量,通过测量结果的统计和分析,揭示排土场散体物料块度组成呈现出比较明显的粒级分级特征。结合试验结果,采用R-R分布函数表达式表示排土场的岩石粒度组成,通过与现场实测粒度组成进行对比,拟合的相关程度相差不大,符合现场实际,分析所得的排土场岩石块度分布规律可为矿山排土场稳定性研究工作提供依据。
Taking the dumping of a dump in a dump in the country as the research object, the distribution rule of the rock mass in the dump was measured by the method of screening, the direct measurement of block and the method of photography - image analysis. By measuring Statistics and analysis of the results reveal that the bulk composition of the bulk material in the dump shows a graded grading characteristic. According to the test results, the RR distribution function expression is used to represent the rock particle size distribution of the dump. Compared with the measured particle size composition in the field, the correlativity of the fitting results is not significant, which accords with the actual situation in the field. The distribution law may provide the basis for the research of the stability of the mine dump.
