Abstract
An air diversion and dust control system for primary use on longwall shearer mining machinery, consisting of directional fluid sprays and passive curtain barriers. The air moving characteristics of fluid sprays are combined with the splitting and blocking characteristics of passive curtain barriers in order to produce an air stream splitting and diversion system which acts to keep dust away from the breathing zone of the machine operator and contained in the area of the coal face until beyond the mining machine. The fluid sprays have a double function in that they both divert and suppress the dust generated during the cutting operation.
