More Information
Summary:The invention relates to the coal mine roadway drivage machinery, in particular to a heavy hard rock tunneling machine which can cut a semi-rock roadway and a whole-rock roadway with high hardness. The tunneling machine solves the problem that the prior mole is not suitable for rock roadway drivage, can greatly improve the drivage working efficiency of the whole-rock roadway, and dramatically reduce working intensity of operators. The tunneling machine has an integral structure with high strength, a complete machine with heavy weight, a horizontal side support arranged on the back of the machine, and a device with high stability; the machine is provided with a mighty dust absorption system and an inside and outside spray dust suppression system, which effectively improves working environment of the operators; a traction of the tunneling machine adopts a full-sealed structure to increase traction driving force and improve propulsive force of the cutting; the tunneling machine has a small assembly, a large diam
