Abstract: Concerned with geology condition，production conditions，mining conditions and rock mechanics, supporting schemes of mine tunnel is an involved problem of theory and technology. Aiming at the above-mentioned problem, the expert system of roadway supporting schemes for coal mine combines expert experience, typical engineering cases and theoretical achievements with artificial intelligence technology; establishes content-rich knowledge base of expert experience, typical engineering cases and theoretical research achievements; adopts initial program for roadway support inferred from two methods of rules and typical cases; builds the program for the roadway support model and compiles into dynamic-link library files loaded and invoked based on the secondary development technology of FLAC3D; realizes optimization of the roadway support on the basis of the initial program and generates sectional chart of roadway support automatically. An application example is presented in coal mine in Shanxi province; the results prove that the system optimization scheme is reasonable and feasible.
