基　　金：The author is indebted to Kurt Douglas and Garry Mostyn for guiding his PhD thesis research program. Not having suffered enough  Garry also reviewed the draft manuscript. Though they greatly helped with the research  the errors and omissions are the authors alone. Many thanks also to Professor Ted Brown for his encouraging comments and his incredible commitment to our profession. He continues to set too high a standard for mortals to emulate

摘      要：This paper presents the results of ongoing research carried out by the author exploring methods to provide a more robust estimate of rock mass properties specifically for use in tunnel *** from various large-scale rock mass failures are introduced,including coal *** damage-initiation,spalling-limit approach is compared to the coal pillar *** comparisons of estimating the geological strength index(GSI)and relationships to estimate the Hoek-Brown failure criterion parameters,mb,s and a,are presented.
