摘　　要：针对大俯采工作面,采煤机设备存在装煤效果差、整机受力变化导致导向滑靴磨损、行走轮啮合位置关系变化、齿轮油位变化的影响。针对大俯采工作面采煤机使用中存在的问题,根据淮北矿务局要求在采煤机上加以改进。成功解决了淮北青东矿30°大俯采开采的难题。For large underhand mining face,shearer equipment exists： coaling poor, the whole force changes lead guide shoe wear, walking gear like positional relationship change, the impact of gear oil change. For large underhand mining face shearer use existing problems. Huaibei Mining Bureau in accordance with the requirements to be improved on the shearer. The successful resolution of Huaibei Mine 30 ° Qingdong big problem prone coal mining.
