Bridge type coal mining machine

The utility model relates to a coal mining machine, in particular to a bridge type coal mining machine which can reduce the minimum thickness of a minable coal layer, increase the coal through height between the coal mining machine and a conveying machine, widen the using range of the coal mining machine, and increase the production efficiency. The bridge type coal mining machine comprises a gap bridge (11), a machine body (9) is arranged on the side end face of the conveying machine (10) near the coal wall side, the gap bridge (11) is arranged right above the working surface of the conveying machine (10), under the gap bridge (11) is a coal through space, the coal mining machine walks along the conveying machine (10) in a reciprocating manner, and the coal through height (d) under the gap bridge (11) is within 30 to 32cm. The bridge type coal mining machine is suitable for the working surface of the comprehensive thin coal mining layer, the minimum minable thickness of the coal layer is small, and the coal t
