平整洁净的运输道,对露天矿和地下矿都很重要,可以提高运输能力,并使轮胎和其它维修费用保持在可接受的水平上。加拿大钱皮恩(Champion)公路机械公司的经验表明,采用大重量、大功率的平路机,是一种明智的选择。功率和重量是评价平路机能力大小的主要判据。用以下两个简单的计算式,可将这两个判据与平路机的能力联系起来: Smooth, clean haul roads are important for both open-pit mines and underground mines to increase transport capacity and keep tires and other maintenance costs at acceptable levels. The experience of Champion Highway Machinery Co. of Canada shows that it is a good idea to use a large weight, high power road roller. Power and weight are the main criteria for evaluating the capacity of a road roller. Use these two simple formulas to relate these two criteria to the grader’s capabilities:
