摘要

Application of bolting and shotcreting used in Chinese coal mine underground engineering has been more than 40 years. By the end of 1993. total roadway length adopted bolting and shotcreting was over 21000km. Now, This paper describes developing and achievement of bolting and shotcreting briefly in the recent years. Meanwhile the paper puts forward solving and improving method for problems which exists in present design and construction. Final, combined with feature of coal mine, the paper puts fotward some proposals about developing of bolting and shotcreting,dynamic management of both designs and construction, engineering measur and stability judgement as
