    (2006) Nawrat, Stanisław; Kuczera, Zbigniew; Napieraj, Sebastian
    Coal seams drainage is made for control of work safety in coal mines. One of the method for coal seams drainage efficiency control is use drainage efficiency factor for provide work safety. Coal seams drainage is depend from a lot of natural and technical factors. Influence of factors for drainage is difficult for qualify, from this reason can be research only in statistical way. Article presents research of influence some drainage parameters for drainage efficiency for exploitation and corridor excavations. Statistical researchers allow to determinate dependence of drainage efficiency from factors like: under pressure in pipe line and density of drainage holes, with can be use in drainage design process, in coal mines.
