5/1/2004 - Conference papersA case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine.
Analyses of Mobile Equipment Fires for All U.S. Surface and Underground Coal and Metal/Nonmetal Mining Categories, 1990-19991/1/2004 - Information CircularsThis report analyzes mobile equipment fires for all U.S. surface and underground coal and metal/nonmetal mining categories by state and 2-year time periods during 1990-1999.
8/1/2001 - Conference papersA statistical study of roof bolt performance was conducted in 37 U.S. mines. Analysis of the results led to guidelines for making preliminary estimates for bolt length, capacity, and pattern to improve roof stability in difficult conditions.
7/1/2001 - Conference papersIn Utah, 3-D, full waveform, autonomous microseismic arrays were placed underground and on the surface of a longwall coal mine with overburden exceeding 750 m. Overall 13,000 seismic events, including a magnitude 4.2 event, were detected and located.
