摘　　要：为了研究桥下采煤对桥梁的影响规律,以新梨公路桥下压煤开采为例,分析桥梁受开采影响的规律,通过调整工作面尺寸、优选开采顺序、减少开采面积等方法,减小了开采对桥梁的不利影响,成功解放桥下压覆煤炭资源,保证了桥梁的安全运营。In order to study the effect of coal mining under the bridge,taking Xinli highway bridge as an example,we analyze the mining influence law under the bridge. By adjusting the size of working face,mining sequence,reducing mining area,we reduce the adverse mining impact on bridge,liberate the coal resources under the bridge,which ensures the safe operation of the bridge.
