Outputs and Transfer - Research Goal 3.1:
Reduce noise on continuous mining machines using coated flight bars

HLR program scientists have transferred the early findings of this research to the industry through conference proceedings, conference presentations, industry/labor workshops, and industry/labor/NIOSH partnership meetings. Technology transfer efforts, such as workshops, conference presentations, and journal articles are selected based upon their ability to reach the most likely users of the research.

Intermediate Outcomes
The coated flight bar chain conveyor is currently being manufactured and sold by Joy Manufacturing, Inc. They produce over 80% of the continuous mining machines in the U.S. MSHA cited this control as a “promising” noise control in the MSHA Program Information Bulletin P04-18, “Technologically Achievable, Administratively Achievable, and Promising Noise Controls (30 CFR Part 62).”[18] In addition, mine operators at two coal mine sites where the coated flight bars have been employed have stated in public meetings that they have observed an audible reduction in the noise level of the continuous mining machine. Miners have also reported to HLR program personnel that the control is easy to implement and has a high level of durability.
