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。
According to the geological conditions of 6202 fully mechanized top-coal caving face, the on-site calculation model is established. Through the analysis of the model’s force and the actual pressure of the transition face, the support force needed for the simple bracket is determined, The minimum amount of support force each support post needs to provide. Not only does the janitor release some of the top coal for roadway transportation, it also enhances the roof control of the lanes near the goaf area.
