煤矿巷道支护方案是涉及到工程地质、生产条件及岩石力学等因素的复杂理论技术问题,煤矿巷道支护方案专家系统针对这一难点,将巷道支护领域专家经验、典型工程案例、理论研究成果与计算机人工智技术能结合,建立了内容丰富的巷道支护专家经验、典型案例、理论研究成果知识库,采用基于规则和典型案例2条途径推理出巷道支护初始方案,运用FLAC^3D二次开发技术建立了巷道支护模型运行程序并编译成动态链接库文件进行加载和调用,实现了基于数值模拟的巷道支护方案优化,并自动生成巷道支护断面图表。以山西某煤矿巷道支护方案设计为例进行应用,结果表明系统优化方案合理、可行。
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 com- bines expert experience, typical engineering cases and theoretical achievements with artificial intelli- gence 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 FLAC^3D; 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.
