    Achieving Non-Duplicated Firing Times in Multipledeck Priming of Individual Blast Holes in Surface Coal Mining Using Non-Electric Down-the-Hole Primers and Electric Surface Initiation

    By James Ludwiczak

    We are coming to an end of an era in Midwest surface coal mining. For many years, large tracts of coal lands were readily available for sale or lease to surface mine operators.
