原始语种摘要: Surrounding rock deformation control (SRDC) of roadways in deep three-soft coal seams (TCSs) is a significant technological difficulty that hinders the safety and high-efficiency mining of coal mines. According to the specific mining geological conditions of Liuquan Coal Mine, this study analyzed the deformation characteristics of surrounding rock under an original support scheme for the headgate (a typical asymmetrical roadway) in #3307 coalface. The analysis results showed that the surrounding rock displayed whole section deformation characteristics. The maximum value of roof subsidence was 369 mm, the maximum cumulative deformation value of the two sidewalls was 784 mm, and the maximum value of floor heave was 386 mm. On this basis, the mechanical structure models (roof, sidewall, and...
