Abstract The development and maintenance of underground roadways are increasingly important aspects of the modern mining process. With the trend toward automation and trackless mining, roadbeds capable of withstanding increased wheel loading have proven necessary to maintain high vehicle speed and reduced
maintenance costs. Concrete has been used successfully on some roadways in order to obtain the required characteristics. However, this solution usually involves unacceptable expense. The objective of the Road Router project was to create a drift floor profiling machine capable of cutting a smooth surface out of the existing rock floor of development drifts and ramps. This surface would provide a durable, high strength, low rolling resistance roadbed that would allow for reduced operating cycle times and lower maintenance costs of scoops and haulage trucks. The Road Router has the potential to offer an alternative to concrete with substantial cost savings.
