MG450/1020-QWD型采煤机在大阳煤矿过构造中的应用

Application of MG450/1020-QWD Shearer Passing though Structures of Dayang Coal Mine

推广使用大功率采煤机是地质构造复杂矿井的必然趋势。通过MG450/1020-QWD型采煤机在大阳煤矿过陷落柱中的实践应用,介绍了该采煤机相比原MG200/500型采煤机的巨大优势。

It is an inevitable trend to popularize the use of high-power shearer in mines with complex geological structures.Through the practical application of MG450/1020-QWD shearer in passing through collapse column in Dayang Coal Mine,this paper introduced the great advantages of this shearer compared with the original MG200/500 shearer.
