  • Shear Strength Evaluation of ClayRock Mixtures
    Shear Strength Evaluation of Clay-Rock Mixtures
    Iannacchione, Anthony T. ;
    Vallejo, Luis E.
    2000/01/01 | Mining Publications
    At present, there is little knowledge concerning the shear strength of clays containing floating rock particles with concentrations from 0 to 30%. In practice, the effect of rock particles is typically disregarded in shear strength analysis. The two primary reasons for this are: 1) a lack of agreement concerning the influence of rock particles on m ...

    2000/01/01 | Proceedings: new technology for coal mine roof support. Mark C, Dolinar DR, Tuchman RJ, Barczak TM, Signer SP, Wopat PF, eds. Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. 2000-151; (IC 9453), 2000 Oct; :81-98 | National Institute for Occupational Safety and Health (NIOSH)
    During the 1990s, the former U.S. Bureau of Mines conducted a number of field studies in which the performance of different types of roof bolts were evaluated in different geologic environments. The studies used a standard suite of measurements, including multipoint extensometers, strain-gauged roof bolts, and roof bolt load cells. The sites were c ...

    Factors Affecting ANFO Fumes Production
    Rowland, James H. III ;
    Mainiero, Richard J.
    2000/01/01 | Mining Publications
    For many years there have been small scale tests available for evaluating the toxic fumes production by cap-sensitive explosives (DOT Class 1. l), but these could not be used with blasting agents due to the large charge sizes and heavy confinement required for proper detonation. Considering the extensive use of blasting agents in construction and m ...
