In an open-cast mine, productivity, fuel consumption and speed of haul trucks are key drivers to improve safety and efficiency of mining operations. To ensure efficient haulage, haul road parameters like rolling resistance, gradient, superelevation, curve radius and road friction must be monitored and upgraded regularly. In Tata Steel Ltd. mines, a multiple-sensor-based measuring instrument was used to capture and maintain the parameters for improving haul roads.
