摘　　要：为了给首采区工作面大采高综放开采设计提供依据,根据首采区地质特征及国内一些产量6.0 Mt以上综放工作面能力的调研情况,分析综放工作面参数变化对生产能力的影响。通过计算表明,9号煤层首采区综放面长度280 m、采煤机截深1.0 m时,生产能力达到最大为7.83 Mt/a。To provide evidence for large-mining-height fully-mechanized mining design in the first mining face, on the geological features of the first mining area and survey results of fully-mechanized working lace productivity with yield more than 6.0 Mt, the paper analyzed the influence caused By parameters on the produetivity. The calculation demonstrated that when the mining face was 280 meters long and miner was 1.0 meter deep, the productivity reached to the maximum value： 7.83Mt/a.
