Abstract：In deep mining，the effective roadway support is an important factor to ensure the safety mining，high production and efficiency. Based on the similarity simulation test and the field test，the fracture characters of the horizontal roadway are studied，which is located in deep tiled strata in Coal Mine No.8 of Hebi Coal Power Ltd.. The law of displacement of roadway，under different applying loads，and the characteristics of development of fracture in roadway and distributions are analyzed. For this geological condition，the more effective support plan is figured out. The study result can be used for understanding the occurrence，development and relationship of the surface of roadway and interior cracks. Based on the results，the support parameters of the roadway can be chosen reasonably. The study methods and results can be used as reference for other similar studies as well.
