Environment monitoring is important for the safety of underground coal mine production, and it is also an important application of Wireless Sensor Networks (WSNs). We put forward an integrated environment monitoring system for underground coal mine, which uses the existing Cable Monitoring System (CMS) as the main body and the WSN with multi-parameter monitoring as the supplementary technique. ...

A new type of cosmic-ray experiment is under construction in the Pyhäsalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 m of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground ...

Through-the-Earth (TTE) communication systems require minimal infrastructure to operate. Hence, they are assumed to be more survivable and more conventional than other underground mine communications systems. This survivability is a major advantage for TTE systems. In 2006, Congress passed the Mine Improvement and New Emergency Response Act (MINER Act), which requires all underground coal mines...

Coal is mined in every country which is mainly used to generate electricity. Thousands of mine workers were killed every year due to many disasters takes place inside coal mine. These accidents are caused mainly due to the leakage of poisonous gas [2] present in the mine. Especially developing countries face a poor safety system for mine workers. Hence it requires a safety monitoring system [1]...

Three types of uncatalyzed diesel particulate filter (DPF) systems, three types of high-temperature disposable filter elements (DFEs), and one diesel oxidation catalytic converter (DOC) were evaluated in underground mine conditions for their effects on the concentrations and size distributions of diesel aerosols. Those effects were compared with the effects of a standard muffler. The experiment...

Robots’ visual perception is a field that is gaining increasing attention from researchers. This is partly due to emerging trends in the commercial availability of 3D scanning systems or devices that produce a high information accuracy level for a variety of applications. In the history of mining, the mortality rate of mine workers has been alarming and robots exhibit a great deal of potentials...

Mobile communication system for underground coal mines is far more behind the one on surface for the unique underground tunnel environment and safety requirements. Though our previous CDMA System V1.0 can solve the problems of coal mine communication well in regular environments, it still remains a challenging issue for emergency handling. In this paper, we propose a novel integrated RFID and s...

Based on continuous revolution of coal mining technology,this paper puts forward a project about safety monitoring system of coal mine using Zigbee technology and RS485 interface. A system is designed using group of sensors which monitors the different environmental condition in underground mines and if value exceeds from threshold value, then the Miners are informed through Alarm. Another modu...
