Abstract: In order to solve supporting design of roadway surrounding rock in Sanjiaohe Mine Coal and provide initial parameters, physical and mechanical properties of roadway surrounding rock were tested and analyzed using laboratory methods. The experimental results show that average density of the lower part of 2^# coal is bigger than that of the upper part of 2^# coal. Average density of the mudstone is similar. The average density of sandstone K8 in the old top is maximum and 2727.15kg/m³. The average values of uniaxial compressive strength of the upper part and the lower part of 2^# coal are respectively 15.53MPa and 9.89MPa. Both of the direct top and bottom are mudstone and the mudstone of the direct top and bottom are respectively 26.13MPa and 54.32MPa. Rock stress-strain curves show variation characteristics of the concave-a straight line-the peak-the destruction in uniaxial compression tests.
