摘　　要：结合6202综放面运输平巷地质条件,建立了符合现场的计算模型,通过对模型的受力分析及工作面过渡架实际压力分析,确定了简易支架所需要提供的支撑力,从而确定了简易支架每个单体支柱需要提供的最小支撑力。该简易架不仅能够放出部分运输平巷的顶煤,同时能够加强平巷靠近采空区区域的顶板控制。Based on the theory of Thai sand, combined with the geological conditions of 6202 fully mechanized face transport drift, more in line with the calculation model is established,based on the model of force analysis and transition of mining face is actual stress analysis to determine the simple support needed to provide support,to determine the simple support each individual prop need to provide the minimum support. The simple coal stent can not only release part of the haulage roadway caving, at the same time to strengthen the roadway near the gob area of roof control.
