Based on large amount of roof subsidence and serious deep separation layer strata behaviors of large span cut eye roadway, 708 working face of Dahuangshan Mine large section cut eye was taken as the background, the characteristics of the large section cut roadway maintenance was analyzed, it was considered that improving the overall stability of surrounding rock and good control of roof and two shoulder angle surrounding rock were the key to realize the good control of such roadway surrounding rock. Based on the analysis, anchor net cable joint control technology was put forward, the engineering practice verified the scientific nature and feasibility of the support technology.
