摘　　要：运用FLAC^3D数值模拟实验和正交实验法,通过以锚杆长度、锚杆间排距和锚索数量作为主控因素分析巷道顶底板及两帮的变形量,确定了影响棋盘井煤矿9^#煤运输顺槽巷道稳定的最大因素,优化巷道支护参数,并得到应对此类巷道支护参数选择的原则.结果证明基于FLAC^3D和正交实验法的巷道支护优化方法与经验法相比有了很大改进.FLAC^3D numerical simulation experiment and orthogonal experiment method are used to analyze the deformation of tunnel roof,floor and two gangs by taking the length of anchor rod,row distance between anchor rods and number of anchor cables as the main control factors,and determine the main factors that influence the stability of 9^#coal seam gateway in Qipanjing mine.The roadway support parameters are optimized and the principles for selecting such roadway support parameters are obtained.The results prove that the roadway support optimization method based on FLAC^3D and orthogonal experiment method has greatly improved compared with empirical method.
