Safe, simple system of bulk handling and loading of ammonium nitrate has proven effective in reducing blasting costs at Pennsylvania anthracite strip mines; prilled AN is received in bulk form in railroad cars; trucks having separate tanks for AN and fuel oil receive their cargo at rail siding; after arrival at blast site AN and FO are mixed as they are discharged from truck directly into vertical boreholes; primary consideration for this system of loading was safety.
