1. A spray system for dust control that operates on a mining floor surface to shear material from a mining wall, the spray system comprising:
a shearer machine comprising a shearer machine chassis, a first ranging arm located on a first end of said shearer machine chassis, and a tail ranging arm located on a second end of said shearer machine chassis,
a set of first ranging arm sprays and a set of second ranging arm sprays mounted on an upper side of a first ranging arm, wherein said first ranging arm is located on a first end of the shearer machine chassis and said set of first ranging arm sprays are directed at an angle between 0 degrees and 45 degrees relative to the mining floor surface and said set of second ranging arm sprays are directed at an angle between 15 and 75 degrees relative to the mining floor surface,
a trailing set of shearer-clearer venturi arm sprays located behind said tail ranging arm and mounted on an operator side of said shearer machine chassis, and
a set of shearer clearer arm sprays that operates in conjunction with a set of shearer-clearer venturi arm sprays located towards a first end of said shearer machine chassis, wherein said set of shearer clearer arm sprays are aligned linearly relative to said set of first ranging arm sprays and reside 2 to 8 feet away from said set of first ranging arm sprays relative to a mining side of said shearer machine chassis and wherein said set of shearer-clearer venturi arm sprays are located on a top surface of said shearer machine chassis and reside approximate to and angled between 105 degrees and less than 180 degrees from said set of shearer clearer arm sprays.
