Alaska rocks 2005: 40th U.S. Rock Mechanics Symposium: rock mechanics for energy, mineral and infrastructure development in the northern regions, held June 25-29, 2004,[i.e. 2005], Anchorage, Alaska, USA
摘要
Acoustic wave detection technique has been developed for over 30 years, whereas the study on the relation between acoustic wave speed and the mechanical characteristics of rock is just on its inception. Based on the geographical conditions of thePansan coal mine of the Huinan coalfield and using analogical simulation experiments and numerical simulation technique, this paper carries out a research on the speed characteristics and their influence factors of the acoustic wave of facies transition rock mass.
