Abstract We conducted one of the first complex geomorphological investigations underground abandoned slate mines in Czechia, Central Europe. Sixty types subterranean geomorphic forms were described from 114 Nízký Jeseník Upland. The forms, evaluated according to their type, scale, frequency, and fragility, are independent each other or embedded. Their cascades occur large multilevel affected by...

The re-identification of coal workers’ pneumoconiosis in Queensland 2015 has prompted improvements exposure monitoring and health surveillance Australia. potential consequences excessive to respirable dust may depend upon the size, shape mineralogical classes dust. Technology now advanced point that characteristics can be explored detail. This research collected samples from four operating unde...

In the pursuit of increased safety the mining industry has worked to develop systems for remote control and autonomous operation of both stationary and mobile equipment. This paper reports on a newly developed system for teleoperation and autonomous tramming of LHD (Load-Haul-Dump) mining vehicles that not only increases the safety of the operators, but also has the potential to increase produc...

Reducing the number of roof fall injuries is a goal of the NIOSH mine safety research program. Central to this effort is the development of assessment techniques to help identify the nature of the risks associated with working under potentially hazardous roof conditions. This paper discusses a method to determine the roof fall risk using a qualitative risk-analysis technique. The ability to det...

With the forecast worldwide capital investment in municipal wireless broadband networks will reach $400 million in 2007 (by Yankee Group), we would need to consider additional benefits from building boom Wi-Fi and WiMAX networks. WiBorne has designed and developed Wi-Fi Citywide projects worldwide during past years, and are realising the benefits of Wi-Fi based location services and innovative ...

Laboratory experiments were conducted to determine the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources. The prototype smoke detector combines optical scattering measurements with ionization chamber measurements in order to reduce/eliminate nuisance alarms due to the presence of airborn...

Auxiliary ventilation of the blind development heading in underground mines is one of the most challenging work activities amongst mining underground operations. The auxiliary forcing ventilation system provides positive pressure, cooling, controlling gas layering, and removing diesel fumes and dust levels from development headings, stopes, and services facilities. The effectiveness of the auxi...

Coal mining in India has a history of over 225 years. The industry currently occupies a covetable third ranking in the world league table of hard coal production after China and the USA. Mechanization has made possible major breakthroughs in coal mining technology. The record of production and productivity of Indian underground coal mines over the years is dismal, to say the least. At the time ...
