Other AbstractAdopting similar material simulation test and numerical simulation methods, the impact damage process of coal roadway under anchor bolt, U-steel and energy absorbing support are studied. The impact failure mechanism of roadway under interaction between coal and support is received. Similar material simulation and numerical results show that the impact damage laws under different support types are consistent with each other. Under impact loads, the roof sinks significant, the floor drum obvious, and the both sides have a large internal deformation; cracks expansion and through, even the coal thrown out. According to similar material simulation test and calculation results, it is shown that for different support types, different levels of impact damage, energy absorbing support has good cushioning and energy absorption characteristics, and advantages of small deformation and good stability. The test results also indicate that the energy absorbing support is better for rockburst roadway.
