Muck Cart

A muck cart is a traditional way of moving excavation spoil from the tunnel face to the starting shaft or entry point. Typically the cart is moved on rails and the tunnel is preferably excavated with a slightly uphill grade to aid in moving the loaded muck cart. Muck car systems are used in person-entry size tunnel diameters. In auger boring systems, a muck skip is used in the launch pit to receive the discharge from the auger.
