介绍了用ＥＫＫＯ探地雷达对华丰煤矿巷道两帮破坏范围进行探测研究的成果，并通过多元回归分析给出了两帮破坏范围与埋深，岩体单向抗压强度，巷道跨度及服务年限之间的关系式，这对类似条件下巷道两帮破坏范围的预测，具有重要参考价值． This paper introduces the research results of using EKKO GPR to detect the failure range of two gangways in Huafeng coal mine and gives the results of multiple regression analysis on the failure range and depth of two gangs, uniaxial compressive strength of rock mass, tunnel span and service The relationship between the years, which under the conditions similar to the prediction of the scope of the two gangway damage, with important reference value.
