摘　　要：公路桥位于山西某矿S1203综放工作面上方,该工作面已推进至公路桥保护煤柱附近,为保证公路桥的安全使用,又最大限度的采出煤炭资源,需对其停采线位置进行优化。在对S1203工作面推进至160、175 m 2种开采方案进行地表移动变形计算的基础上,对公路桥受综放工作面开采影响程度进行了分析。结果表明:综放工作面推进距离为160 m较为合理。The highway bridge locates above the S1203 fully mechanized mining face of a mine in Shanxi. The working face has been pushed up to the protection pillar of the highway bridge. It is necessary to optimize the location of the stop mining line in order to ensure the safe use of the highway bridge and maximize the recovery of coal resources. On the basis of calculating the surface movement and deformation of two mining plans advancing from S1203 working face to 160 m and 175 m. The influence degree of mining on fully mechanized mining face about the highway bridge is analyzed.The results show that the advancing distance is 160 m, which is more reasonable.
