摘要
阐述了正交试验设计方法(OEDM)的基本原理,分析了影响厚煤层巷道围岩变形与破坏的主要因素。在对具体矿区工作面石炭系厚煤层工程地质条件分析的基础上,应用FLAC3D数值计算软件,构建了基于OEDM的厚煤层回采巷锚杆支护FLAC数学分析模型。工程实践表明,所建立的正交数值试验锚杆支护设计数学模型,能满足厚煤层巷道围岩控制的实际需要,该方法可为同类条件下厚煤层回采巷锚杆支护设计提供一定的技术指导。
In this paper,the basic principle of the orthogonal experimental design method( OEDM) was described,and the main factors affecting the deformation and failure of surrounding rock of the roadway in the thick coal seam were analyzed. Based on the analysis of the engineering geologic condition of the thick coal seam in Carboniferous System in a coal mining area,the FLAC mathematics model of mining roadway bolt support design based on OEDM was established by using FLAC3 Dsoftware. The engineering practice indicated that the established orthogonal numerical experimental model for bolt support design could meet the actual needs of the surrounding rock control of the roadway in the thick seam,and this method could provide a certain technical guidance for the bolt support design of the roadway in the thick seam with the similar conditions.
