Abstract There are a lot of successful examples in coal mining working face internal probe of concealed structure for Radio wave perspective technique,but less research on the resolution and limitation of the method for the collapsing column probe was done.In order to illustrate the reliability and limitation of the method detecting the collapse column,numerical simulation and practical perspective instances are discussed from two aspects, numerical simulation method are adopted to simulate the collapse response in working face and the forward date was carried out on the inversion, The radio wave perspective method for isolation of single or multiple collapse column has a high degree of differentiation, the inversion position matches the reality highly, actual engineering example proved that the conclusion of numerical simulation,for collapse columns which transverse position differ little,the distinguish ability decline,resolution enhancement is limited by the construction method.
