| 摘 要： | 分析了不同压帮方式的内排运距特点与计算原理,建立了内排压帮高度及重复剥离深度的数学模型,得出通用的计算公式并给出有效判据。以黑岱沟露天矿为例,采用费用补偿法确定最优的内排压帮高度,利用最小重复剥采比确定最佳的重复剥离深度。研究结果表明:分区开采露天矿相邻采区间内排压帮高度与重复剥离深度需同时确定,以费用补偿法建立的数学模型简单且可靠,研究成果对露天矿相邻采区间生产设计具有指导意义。

| Abstract: | Features and calculation principles of inner dumping haul distances for various types of inner dumping covering are analyzed, mathematical modes about inner dumping covering height and repeated stripping depth are set up, and some general calculation formulas and feasible criteria are given. Taking Heidaigou surface coal mine as an example, we adopt a method of expense compensation to determine the optimal inner dumping covering height, and use the minimum repeated stripping ratio to determine the best repeated stripping depth. Results show that inner dumping covering height and repeated stripping depth must be determined at the same time, and the mathematical modes established by the method of expense compensation are not only simple but reliable. In addition, the research results can provide reference for the production of adjacent mining area in surface coal mines. |
