Abstract
This paper presents the results of two recent Bureau of Mines sponsored programs related to noise control in coal preparation plants. These programs were aimed at evaluating engineering controls for reducing the occupational noise exposure of plant workers. The first of these two programs evaluated the performance of various noise control techniques in an operating preparation plant. Four general categories of noise control treatments were selected, installed, and monitored over an extended period of time to evaluate their acoustic performance and durability. The four categories were resilient screen decks, resilient impact pads, chute liners, and mass-loaded curtains. This program demonstrated that the treatments can be both effective (providing 5 to 10 dBA of noise reduction) and durable (with effective service lives of 1 to 4 yr). The second project focused on documenting noise control treatments that can be incorporated into new coal preparation plants at the design stage. While some of the treatments considered were similar to those evaluated in the previous project, a number of additional techniques were also considered, such as equipment substitutions and changes in plant layout. Consideration of these techniques is possible for new plants because of the design flexibility provided during the planning stage of a new facility.
