  • The Charge Distribution of Indoor Aerosol Particles
    The Charge Distribution of Indoor Aerosol Particles
    Li W
    2001/08/01 | Grant Final Reports
    The majority of aerosol particles in indoor occupational environments are 10-500 nm in diameter. Recent studies with human lung cast (Cohen et. aI., 1995) have shown that the charged particles deposit five times more efficiently than the zero-charge particles in the size range of 20 - 200 nm. The significant implications of this increase in deposit ...

    Roof falls continue to be the greatest single safety hazard faced by underground coal miners. During 1996-99, 44 coal miners lost their lives in rock falls and nearly 2,400 were injured. In addition, nearly 6,000 noninjury roof collapses were reported. Roof supports are installed to protect the miners, but support system failures contributed to mos ...

    The risk of injury caused by minor roof falls continues to increase in underground mining. Most ground control injuries result from small rock falls that occur in a supported area, but do not involve the failure of the support system. In the roof, these are the "skin failures" that occur between previously installed primary or secondary bolting sys ...
