| 英文摘要 | The comparison of mechanical properties of hard coal under different conditions is important for the occurrence of coal mine dynamic disasters. This study adopted six tests, namely, the static tensile test, static tensile test, dynamic compressive test, dynamic tensile test, and coupled dynamic-static tensile and compression test, to analyse the relationship of the mechanical properties of coal under different conditions. The results show that, first the tensile strength of this type of hard coal under dynamic loading is 2-7 times higher than that under static loading. Second, the static tension-compression ratio is between 1/16 and 1/64, and the dynamic tension-compression ratio is between 1/2 and 1/40. The tension-compression ratio of coal is approximately three times higher under dynamic loading compared with that under static loading. Lastly, the dynamic strength increases with the axial static load within a certain range, but the dynamic strength of coal may decrease beyond this range.
