8/1/2003 - Conference papersA multi-body biomechanical model was developed that can be used to assess the risk of low back disorders due to occupational exposure to jarring and jolting from operation of heavy mobile equipment (e.g., trucks, haulers, graders, tractors, etc.)
-
8/1/2003 - Conference papersRoof Monitoring Safety Systems (RMSS) were installed in 13 underground limestone mines in 6 states. This paper analyzes the data obtained at three of the mines and provides an overview of the system, data, analysis and applications relevant to RMSS.

8/1/2003 - Conference papersPumpable roof supports provide an alternative longwall tailgate roof support and have grown in usage recently. Despite the success of these supports, questions remain regarding critical design issues for optimizing the use of this technology.
-
8/1/2003 - Conference papersThe purpose of this paper is to evaluate the preliminary findings of a long-term underground study of various types of surface support liners, and to examine installation practices that are critical for an effective liner material application.

8/1/2003 - Conference papersA three-step method is presented to determine nonlinear stress-strain curves for boundary-element programs used in many mining applications. The method requires a suite of laboratory-scale strength tests at various confining pressures.
-
8/1/2003 - Conference papersThis paper presents information that shows that short-encapsulation pull tests can provide the information necessary to improve ground control in variable roof conditions.
-
8/1/2003 - Conference papersStanding crib supports have been applied in underground mining programs to resist large roof movements and sustain high-loads. The parameter that has not been examined and is not well understood is the effect that a crib or other types of standing supp...

8/1/2003 - Conference papersA field study was conducted to evaluate four seat designs on shuttle cars, including two NIOSH-designed seats.
-
8/1/2003 - Conference papersNIOSH is conducting research to develop mine design algorithms that will result in safer multiple seam mines. This paper presents an overview of multiple seam issues in the central Appalachian coalfields.
-
8/1/2003 - Conference papersThis paper describes two tools NIOSH developed. The miniature data acquisition system (MIDAS) could make geotechnical instruments in underground mines more feasible. The rock strain strip, together with MIDAS, more accurately measures rock movement.
