摘　　要：为了保证露天煤矿生产能力核定的科学性,分析了采煤能力和剥离能力单独核定的问题以及年推进度、年降深速度、边坡稳定、咽喉道口车流密度对生产能力的影响。结果表明:采煤能力和剥离能力应分别进行单独核定,须考虑年推进度、年降深速度及边坡稳定的影响因素,并对露天矿的咽喉道口进行车流密度验算,分别核算各个采装设备的工作线长度和工作面数量,从而确保生产能力核定的准确性。In order to ensure the scientific nature of production capacity verification in the open-pit coal mine,the article analyzes the verification of coal-mining capacity and stripping capacity and the influence of annual advancing speed,annual descending speed,slope stability and traffic density at throat outlet on production capacity.The results show that:the ability of coal mining and stripping are separately for verification.We must consider the affected factors of annual advancing speed,annual descending speed,slope stability,calculate the open throat crossing traffic density and check mining equipment work line length and the number of working face,in order to ensure the accuracy of the production capacity verification.
