摘要:
采用地应力椭球和地应力椭圆分析方法,结合实测的车集矿地应力结果,以及矿区地质资料、地应力测量中揭露的地质情况,研究原岩应力与巷道松动圈的关系.结果表明:在地应力作用下,不同的巷道走向将影响到其周边围岩的受力状况,随着地应力椭圆离心率的增大,巷道周围受力的不均匀性增加.走向一定的情况下,将应力椭圆视为围岩破碎带的形状,从而进行巷道断面形状的优化和支护参数的优选是合理可行的.
Abstract:
Based on the in-situ geo-stress data of Juji mine,and combined with the mine geological data and the geological conditions obtained in the geo-stress measuring process,the method of the stress ellipsoid and ellipse is used to study the relationship between in-situ rock stress and the roadway loose circle.The results indicate that: under the action of geo-stress,different roadway strike will affect the force condition of the surrounding rock; the non-uniformity of roadway force increases with the increment of stress ellipse eccentricity.To certain roadway strike,it is reasonable and feasible that the roadway cross-section shape and support parameters are optimized by regarding the geo-stress ellipse as the shape of rock fracture zone.
