| Abstract: | The stripping blasts to the opencut coal mine of Urumqi Mineral Bureau caused selective damage to the houses in Tiechanggou Village 1 km from the blasting site,and different houses sustained damage very differently.Through investigation and analysis it is thotght that the selective damage is because that people leveled ground in small area,thereby producing free interfaces beside house base and droping the antiseismic ability of the houses.This knowledge will have certain reference value in such aspects as earthquake resistance and protection as well as earthquake disaster prediction,etc.. |
