摘　　要：在分析了矿石损失与矸石混入模型存在的问题与不足的基础上,假定筒式露天采矿机开采底线在矿石与矸石分界线上下一定范围内变动,根据总损失最小的原则建立了矿石损失与矸石混入优化模型,并利用模型结果给出了露天采矿机矿层选采厚度的确定方法。对国内某大型露天煤矿的实例研究结果表明,优化模型在露天采矿机的一个切削周期内可以为该矿减少损失6.572元,优化模型更加合理。After analyzing the problems and shortcomings existing in the model of mixing ore loss and gangue, the paper supposed the mining bottom line of the drum-typed surface miner ranged from ore boundary to gangue boundary, and built the optimization model of mixing ore loss and gangue according to the principle of minimizing the total loss. And then, the model results were used to offer the method of determining the mining thickness of the surface miner. The application in a large domestic surface mine showed that the loss of 6.572 RMB could be avoided during a cutting cycle of the surface miner and the optimization model was more reasonable.
