摘　　要：针对某矿提出对MG900/2245-GWD型采煤机进行改造,实现6.2-6.7 m特厚煤层开采的要求,从最大采高、工作性能和工作面三机配套3方面分析了MG900/2245-GWD型采煤机进行改造的可行性,制定了改造方案,对存在的潜在问题,采取了相应的改进措施。工业性试验结果表明,改造后采煤机的各项功能、整机可靠性和产量均达到了预期要求。In the light of a mine＇s requirement of enlarging MG900/2245-GWD shearer＇s mining height to 6.8 m,analyzed the feasibility from the maximum mining height, working performance and matching of coal mining face hydraulic supports,conveyor and shearer, made improvement plans,and took corresponding measures for potential problems. The industrial test results showed,improved shearer＇s function,reliability and output reached the expected requirements.
