Abstract
Mining equipment adapted for repeated traversing to and fro adjacent to a conveyor arranged along a longwall face in an underground mine, has a mining machine support structure which bridges the conveyor and which has a curtain for guiding airborne dust arising during cutting of mineral by a rotary cutting head mounted on the machine. The air flow passage defined by the curtain has an air flow inducing means therein, such as a fan or water spray.
Claims12
Mining equipment adapted for repeated traversing to and fro adjacent to a conveyor arrangable along a working face in an underground mine, the mining equipment comprising a mining machine bridge structure adapted to bridge over the conveyor, means which, in use, enable at least a portion of the bridge structure to traverse along a path spaced from the conveyor, and an airborne dust guide curtain means extending along and downwardly from opposed side portions of the bridge structure along a major portion of its length and downwardly towards opposed sides of the conveyor to define side walls of an open ended passage extending longitudinally beneath the bridge structure, the curtain means being arranged to negotiate undulations in the conveyor.
