摘　　要：爆轰波在岩层传播的衰减特性使得采空区周围的电阻率分布发生规律性变化。基于此变化规律,使用超高密度电法勘探采空区周围电阻率分布并对电阻率沿爆轰波传播方向进行拟合计算,采空区边界与其一阶导数数值最大区域相切。结合相邻测线的勘探结果可以得到采空区空间位置、走向以及体积等参数,为采空区的治理提供了精准有效的数据支撑,从而减少了采空区带来的安全危害。The propagation attenuation characteristics of detonation wave caused the distribution of resistivity around the goaf with a regular changing. Based on the rule, ultra-high density resistivity method was used to prospect the surrounding resistivity distribution and fit the resistivity along the direction of detonation wave propagation. It concluded that the goaf boundary was tangent to the maximum area of the first derivative value. Moreover, the position, direction, size and others parameters could be obtained through the comprehensive analysis of the adjacent line of exploration results. Therefore, the study can provide accurate and effective data for goal management so as to reduce the safety hazards.
