National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Dust Sources and Controls for Multiple-Machine Longwall Faces.

PB95220141

Publication Date	1995
Personal Author	Colinet, J. F.; Spencer, E. R.
Page Count	18
Abstract	Longwall mining in lower seam heights may necessitate the use of single drum shearers to overcome size constraints associated with standard double-drum shearers. In an effort to evaluate the unique dust control problems associated with this type of mining, the U.S. Bureau of Mines conducted dust surveys on two multi-machine longwall operations. Sampling was conducted to quantify major sources of respirable dust and to identify potential solutions to overcome problem areas. Sampling results indicate that the cutting sequences utilized on multi-machine faces may have to be designed to minimize dust exposure, as opposed to optimizing productivity or operational requirements.
