露天矿的管理者通常认为,道路不铺设底基层所节省的资金,可弥补在生产中由于道路破坏而引起任何可能的损失。按照《露天矿道路设计》(《Design of Surface Mine Haulage Roads》)手册中所述,这种作法在实践中所产生的结果几乎总是不理想的。由于在路面下缺乏适当的承重材料,道路会产生大量的车辙、沉陷和全面 The managers of open-pit mines generally believe that the savings in roads that do not have a basement layer can make up for any possible damage caused by road damage during production. According to the “Design of Surface Mine Haulage Roads” manual, the results of this practice in practice are almost always unsatisfactory. Due to the lack of suitable load-bearing materials under the road, the road will produce a lot of ruts, subsidence and full
