摘要
乌鲁木齐矿务局露天矿的剥离爆破对距爆点１ ｋｍ 外的铁厂沟村房屋产生了选择性破坏，振动对个体房屋的破坏呈现出鲜明的选择性，不同房屋遭受的破坏程度差异极大。考察、分析后发现，选择性破坏是由于人工小面积平整改造地形使房屋基础外围形成自由面，降低了房屋的抗震性造成的。
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..
