The need to improve productivity and to meet the growing demand for coal has prompted the coal industry to shift to greater utilization of longwall mining. Although longwall mining offers many advantages, there is a severe problem in the control of respirable dust and in the ability to comply with the 2-mg/m3 federal dust standard. The Bureau of Mines has been aggressively seeking solutions to the problem for several years and has successfully demonstrated cost-effective engineering controls that are available for immediate application. Although substantial progress has been achieved, because of the complex and interactive factors involved, not all of these improved techniques are applicable on every longwall installation. Physical characteristics on each panel directly impact the dust control requirements to be implemented. In addition, many new procedures have been developed but not evaluated under the diverse conditions encountered throughout the industry. In response, the Bureau has undertaken a major joint effort with industry to identify and document technology that may eliminate the longwall dust problem.
