The Scientific Basis for Evaluation of the Methane Problem in New Mines.
Proc West Virginia Coal Mining Inst 1970 Oct; :19-23
The design and development of new mines, especially in coalfields where there is little or no recent experience, is often hampered by lack of knowledge of potential methane control problems. Ventilation system layout, total air requirements, and rock dust supply are only a few of the factors directly dependent on methane emission, but ultimately the productivity of the mine may depend on the capability of mine management to control methane which may, in fact, overwhelm all other considerations. Even mines which have been in production for decades, using a conventional "cut-drill-load- shoot" mining system, may encounter severe methane control problems after converting to a continuous boring-type machine mining system. The reasons for this can be explained best if how methane is present in coalbeds is understood.
