Snowfall can lead to the cessation of production in a truck-shovel mining system. A snow road removal procedure that is performed simultaneously with the production operation is introduced to avoid this situation. A discrete-event simulation model is built to evaluate both operations under different configurations. An operation policy is designed based on the simulations results. This policy defines the manner in which production and snow removal operations are conducted depending on the intensity of the snowfall. The operational policy demonstrates that production can be maintained at high snowfall intensities.

降雪事件的离散事件模拟设计露天矿生产策略

降雪可能导致卡车铲式采矿系统停止生产。为了避免这种情况，引入了与生产操作同时执行的雪道清除程序。建立了离散事件仿真模型，以评估不同配置下的两种操作。根据仿真结果设计了运行策略。该政策定义了根据降雪强度进行生产和除雪作业的方式。运营政策表明，可以在高降雪强度下维持生产。
