As the utilization range of smart devices for infrastructure has widen its application owing to flourishing of smart devices, studies on the technologies to graft IT onto underground utilities are actively carried out. In particular, as underground utilities have a characteristic of invisibility, studies on a management system converged with augmented reality are demanded for the efficient mana...

In order to reliably monitor the operating status of one-way aerial ropeways for underground mine and better guarantee the safety of mine personnel, a hierarchical routing protocol based on energy efficiency and chain-type structure is proposed in this paper. Previous studies show that uniform cluster formation can prolong the lifetime of network. So a novel time allocation algorithm based on t...

This paper examines the kinematics and control of a Load Haul Dump Vehicle used in underground mining operations. The aim of the work is to develop an autonomous guidance strategy. A linear, state-space, mathematical model of the vehicle is derived purely from geometric consideration of the vehicle and its desired path. Autonomous regulation of the vehicle is shown to be theoretically feasible ...

A Wireless Underground Sensor Network (WUSN) is a network of wireless sensor devices in which all sensor devices are deployed completely underground (network sinks or any devices specifically for relay between sensors and a sink may be aboveground). These networks can be utilized to monitor the underground environment, especially soil conditions and aboveground events, such as the presence of p...
