Abstract

The underground gas explosion test model to detect intensity of the mine refuge shelter is simulated through LSDYNA to obtain the surface pressure of the mine refuge shelter in underground gas explosion, using the TNT to replace the mixture gas. Pressure distribution of the front shelter is descending from the bottom to the top, and from the middle to both sides, which is about 0.4410~0.5326MPa, the duration is 242.5ms. After the maximum pressure peak, there are several smaller pressure peaks. Pressure distribution of the back shelter is descending from the bottom to the top, and from the middle to both side, which is about 0.2027~0.3144MPa. With the distance to the front increases, pressure distribution of the top and side shelter is descending, but the extent of descending is small, which is about 0.27MPa.
