Studies conducted on surface coal mining equipment have identified whole-body vibration as a significant hazard. Operators of underground mobile equipment, particularly shuttle cars and transport vehicles, are likely to be exposed to significant levels of whole-body vibration. To date, measuring whole-body vibration from underground mining mobile equipment has been difficult due to the strict g...

The passive infrared (IR) imaging signature of buried mines under three different soil surface conditions is investigated in this work. The three-dimensional (3-D) nature of the mine, the site, and the temporal attributes of surrounding climate and exposed radiation are accounted for large and moderate-scale clutter surfaces as well as a smooth surface. The effect of the shortand long-wavelengt...

The extensive use of diesel-powered equipment in mines makes the exposure to diesel aerosols a serious occupational issue. The exposure metric currently used in U.S. underground noncoal mines is based on the measurement of total carbon (TC) and elemental carbon (EC) mass concentration in the air. Recent toxicological evidence suggests that the measurement of mass concentration is not sufficient...

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...

Hodnotenie nebezpečnosti banských plynov v uzavretej čiernouhoľnej bani „Niwka-Modrzejów” Closing of hard coal mines, especially stopping the process of mine water pumping, results in a reconstruction of the Carboniferous water-bearing horizon, leading to the intensification of gas flux to the near-surface zone („piston effect”). Stopping the fans considerably enhances the movement of mine gase...
