 MZ series Coal Mining Machine of Screw Driller is composed of mainframe, hydraulic system, electrical control system, ventilation system, spiral drills. The machine adopts the technology of single-head drilling, namely, coal mining machine is fixed in the gate and drills hole for coal seams, and the bit cuts the coal, spiral drilling rod collects coal, then coal falls in the gate directly and be shipped out. This series coal mining machine is applicable for thin seam coal mining of stiffness f＜6, thickness 0.5～0.9m, its mining width is 1.305～2.105m, mining depth can arrive 80m, and can apply to the roadway section 7.6～14m2.
