摘　　要：基于甘庄煤矿近距离煤层巷道锚杆锚索联合支护参数设计,从近距离煤层巷道围岩实际及本矿巷道支护现状出发,采用MIDAS/GTS数值模拟,分析了近距离煤层巷道围岩位移、应力分布及破坏范围;研究了不同因素对巷道围岩变形与破坏的影响,设计得出合理的支护参数,进而提高锚杆锚索联合支护参数设计的科学合理性及实用可靠性,进一步发挥锚杆支护技术的潜力,为近距离煤层巷道支护提供理论依据及技术支持。Based on bolt and cable support parameters design about close coal seam in the Ganzhuang coal mine, starting from the aetual distance seam roadway for the mine roadway support the status quo, by MIDAS / GTS numerical sinmlation, analysis distance seam roadway fordisplacement, stress and the extent of damage distribution, supporting the body force status; different factors impact on the surrounding rock deformation and failure of different support parameters supporting effect; through the program, determine reasonable support parameters. Designed to improve the bolt and cable support parameters scientific rationality and practical reliability, and further play to the potential of bolting technology the, close coal seam support care to provide a theoretical basis and technical support.
