摘　　要：本文在对井下实际开采条件及受护对象研究基础上,确定采用条带工作面布置及限厚开采的方法,以此来减小采动对公路的影响程度。借助概率积分预计方法确定最佳采高,保证公路安全正常行车要求。通过对现场实际观测资料统计与分析,研究了采动影响下公路变形机理,为类似条件下过公路采煤提供技术参考。Based on the study of the actual mining conditions and the protected objects in the underground mine,this paper determines the method of strip face layout and thickness limit mining,so as to reduce the influence of mining on highway.And with the help of probability integral prediction method to determine the best mining height,to ensure highway safety normal driving requirements.Through the statistics and analysis of the actual observation data,the deformation mechanism of highway under the influence of mining is studied,which provides technical reference for coal mining under similar conditions.
