摘要
采用探地雷达技术对隐伏采空区进行精确勘探,从理论上分析了采空区目标提取以及目标体的空间位置,为实际操作提供依据,建立平面域弧面顶板模型,对采空区、围岩裂隙和顶底板裂隙的波形,破碎围岩对采空区的影响以及不同充填体情况下采空区反射波形特性进行分析。
Using GPR technology to accurately explore the hidden goaf,this paper theoretically analyzed the goaf target extraction and the spatial position of the target body,which can provide the basis for the actual operation.The plane arc roof model was established.The waveforms of goaf,surrounding rock fracture and roof and floor fracture,the influence of broken surrounding rock on goaf and the characteristics of goaf reflection waveforms under different filling conditions were analyzed.
