摘　　要：传递岩梁法计算出维护工作面需要的支护强度,依据煤层赋存条件,初步选出支撑掩护式ZZ5400/13/24和掩护式ZY5400/12/24这2种架型,通过对比分析支架固有力学特性,结合工作面地质赋存条件,得出支撑掩护式支架更适合岩梁强度较高的工作面。The support strength required to maintain the working face is calculated by the transfer rock beam method,according to the occurrence conditions of the coal seam,two types of support about standing shield support ZZ5400/13/24 and shield support ZY5400/12/24 are preliminarily selected,analysis of the inherent mechanical properties of stents by comparison,combined with the geological occurrence conditions of the working face,it is concluded that standing shield support is more suitable for the working face with higher rock beam strength.
