ABSTRACT
Mining companies are looking for higher productivity solutions for low and medium-thickness potash seams. The suitable approach is high-speed cutting longwall-mining. Many specialists propose to use Interferometry of Synthetic Aperture Radar (InSAR) technology to control the deformations of rock's massif surface. Unfortunately, it is not possible to retrieve the full displacement vector from a single InSAR measurement. This chapter proposes some heuristic methods based on the hypothesis of a physical relation between horizontal and vertical displacements. To investigate the reason of phenomena, the special numerical model was developed that provide to simulate high-speed longwall-mining. The goal of such developments was to find the way for estimation maximum of absolute vertical displacement/zero horizontal displacement (MVD/ZHD) divergence to improve InSAR deformation measurements. The future improvement of presented numerical model can lead to accurate estimation of MVD/ZHD divergence and as result to increase accuracy of InSAR measurement for potash mining.
