Abstract:

In the use of the heading machine through fault upgoing high-angle roadway construction, especially track slip and unstability of the machine through fault, by increasing the heading machine crawler with bottom friction, cutting head power, optimizing the cutting line and using the way of caterpillar's rotation traction runway, we cccelerate the driving speed, simplify working processes and reduce the labor intensity, and then implement the heading machine in the successful application of the high-angle bord-up construction. Break through the slope limit of high-angle roadway upgoing construction, for the heading machine through fault high-angle roadway construction accumulated the experience.

Key words: tunneling, fault, high-angle, upgoing, cutting line
