摘　　要：近距离煤层在我国分布广泛,近距离煤层支架选择是开采中的重要问题。根据理论分析和数值模拟方法,分析近距离煤层应力分布和液压支架选型依据,得到模拟工程条件下的合理支护强度为1.2 GPa,并得到液压支架架型选择和优化参数。Close coal seam are widely distributed in our country,the stent is an important issue in production of close coal.According to theoretical analysis and numerical simulation method, analysis of the stress distribution of coal seam and the selection of the hydraulic support up close can obtain by this way.Simulative project under the condition of the reasonable supporting strength is 1.2 GPa, and get the type hydraulic support frame parameter selection and optimization.
