1 Atract-Falling of mine through air, water, and sediment is investigated experimentally and theoretically. Two experiments were conducted to drop cylindrical mine with the density ratio around 1.8 into shallow water (around 13 m deep) in the Monterey Bay (Exp-1) and into the Naval Postgraduate School’s swimming pool (Exp-2). During the experiments, we carefully observe mine track and burial de...

This work investigates the dynamics of heavy articulated vehicles and the problem of yawinstability caused by loss of traction. A mathematical model of the system is derived and applied to a typical vehicle used in mine haulage applications. Automatic control, based on differential wheel braking, is explored by simulation and shown to be potentially valuable in improving the safety of such vehi...

In the theory of traffic flows the main characteristics are: intensity, speed, and density.  They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...

RECENT investigation of samples labelled zaratite from the Lord Brassey Mine, near Heazlewood, Tasmania, in the mineral collection of the Museum of Victoria revealed the presence of the rare nickel carbonate, otwayite, and the rare nickel hydroxide, theophrastite. X-ray diffraction, electron microprobe and infrared analysis were utilised in the study, which failed to confirm the presence of zar...

Typically thermal power plants are located near to surface coal mines that produce huge amount of fly ash as a waste byproduct. Disposal of fly ash causes significant economic and environmental problems. Now-a-days, research is going on for bulk utilization of fly ash. In order to increase its percentage utilization, an investigation was carried out to evaluate its potential for haul road const...

The quality of the road pavement has always been one of the major concerns for governments around the world. Cracks in the asphalt are one of the most common road tensions that generally threaten the safety of roads and highways. In recent years, automated inspection methods such as image and video processing have been considered due to the high cost and error of manual metho...
