  • Design of Roof Bolt Systems 2000
    Design of Roof Bolt Systems [2000]
    Mark, Christopher
    2000/10/01 | 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; :111-131 | National Institute for Occupational Safety and Health (NIOSH)
    Roof bolt system design means the selection of the type, length, capacity, and pattern of bolts for a particular application. Despite research efforts dating back 50 years, no design methodology has found wide acceptance. This paper begins by identifying four mechanisms that roof bolts use to reinforce the ground. It argues that the reinforcement m ...

    Barczak, Thomas M.
    2000/10/01 | 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; :207-221 | National Institute for Occupational Safety and Health (NIOSH)
    The safety of mine workers depends on the proper installation of roof supports to prevent the ground from collapsing into the working areas of an underground mine. As new support systems are developed, they need to be properly evaluated to make sure that they are capable of providing adequate roof support before they are first used in a mine. In ad ...

    Barczak, Thomas M.
    2000/10/01 | 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; :193-206 | National Institute for Occupational Safety and Health (NIOSH)
    Secondary roof support systems play a vital role in preserving the safety of underground mine workers by preventing the unintentional collapse of the mine roof. Hundreds of thousands of standing roof supports are constructed each year in underground coal mines. Historically, wood and concrete cribs and timber posts have been use for secondary roof ...

    Barczak, Thomas M.
    2000/10/01 | 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; :245-252 | National Institute for Occupational Safety and Health (NIOSH)
    Purchasing a new set of longwall shields requires a substantial investment. A poor shield design can lead to economic hardships, safety concerns for the mine workers, and closure of the mine. This paper addresses several key points that should be considered in the procurement process: (1)understanding your goals and the logic in selecting a higher ...

    Macrophage transfection studies are crucial for understanding gene regulation and expression. However, gene transfection in macrophages is difficult. We have shown here that macrophages are more resistant to gene transfection compared with other cell types. To further develop an efficient gene delivery system for macrophages, we evaluated various l ...

    We have investigated the role of inflammation in toxicant-induced glial activation using a well-characterized model of hippocampal neuronal damage (trimethyl tin- TMT) in the rat. Despite the potential role of inflammation in glial reactions associated with neurological diseases, such as Alzheimer's disease, we find very limited involvement of pro- ...

    It is now widely accepted that astrogliosis represents a dominant response of the adult central nervous system to all types of injuries. This "reactive" state of the astrocyte can be induced by a diverse array of toxic substances as well as by neurological disease states and traumatic or ischemic injuries. Historically, astrogliosis was viewed as a ...
