摘　　要：在分析道清矿地质条件的基础上,结合现有锚杆(锚索)支护理论、影响锚杆支护可靠性因素,并针对大倾角煤层的巷道围岩变形特征,采取非对称性支护方式。用数字矿山管理软件中的巷道设计支护子系统为道清矿进行锚杆支护设计,通过计算机软件进行支护方式的选择、断面形状的选择、为巷道围岩设定围岩系数、设定围岩参数等,使计算机自动生成巷道断面图。节省了工作量,同时保证了支护设计的准确性、科学性,为巷道支护设计领域开辟了新的途径。On the basis of analyzing geological conditions in Daoqing Mine, combining existing anchor support theory and the factors which influenced its reliability, according to the the surrounding rock deformation and failure characteristics of inclined eoal seam, the asymmetry supporting method is taken. The design of roadway support subsystem of digital mine management software is used to design bolting support for Daoqing Mine. The computer software is used to choose the supporting method,select section shape,set coefficient of surrounding rock and make the computer automatically generate section chart of roadway. This saves the workload and guarantees the accuracy and scientific of the supporting design at the same time, which starts a new field for roadway support design.
