The utility model relates to a coal-mine laneway excavating machine, in particular to a narrow excavating machine which can cut a full-rock laneway or a half-coal rock laneway with middle hardness. The utility model solves the problems of that the prior excavating machine is not suitable for a small profile laneway excavating, the walking is not stable and is easy to slide to the side and the walking part retaining coal and the rock device is not prefect, etc. The excavating machine can largely improve the work efficiency of the excavation of the small laneway, largely reduces the work strength of the operator, and improves the reliability. The utility model has a narrow overall width and the upper half part is narrower than the walking part, which can avoid the ventilation pipe in the laneway, and the utility model is suitable for the small profile laneway excavation operation. The walking part of the utility model adopts a fully enclosed structure; the transverse bracing of the rear support leg increases a side sliding-proof capability of the device, improves a thrusting force of the cutting part, thus making the utility model have a capability of the full rock or half rock laneway with the middle hardness (f7).
