Abstract

The invention provides a time-space characteristic and cross-border mining identification method for multi-source data monitoring mining area deformation. The method comprises the following steps: firstly, obtaining and optimally processing data by using a synthetic aperture radar (SAR); fusing SAR data monitoring data of a multi-satellite platform to obtain a settlement result map; carrying out supplementary monitoring on 'a large-deformation area' or 'a de-coherence area' in a tested mining area in the fused settlement result map; unifying multi-satellite platform data monitoring result coordinates; and finally inverting time-space characteristics of surface deformation of the mining area, so as to identify a cross-border mining area. The method is simple, small in calculated quantity and high in identification efficiency, and has important theoretical value and a wide application prospect in the aspects of maintaining the mining order, ensuring the mine safety and protecting the ecological environment of the mine; and the time-space characteristics of surface deformation of the mining area can be effectively inverted.

Description

technical field [0001] The invention relates to a time-space characteristic and an identification method for out-of-boundary mining, and is especially suitable for multi-source data used in mine safety monitoring to monitor the time-space characteristics of deformation in mining areas and an identification method for out-of-boundary mining. Background technique [0002] Surface subsidence in mining areas is a real problem faced by every mining area. The surface subsidence of the mining area affects the normal mining order to a certain extent, and when the subsidence is very serious, it will affect the safety of mining activities. The existing technical means for monitoring the settlement of mining areas mainly include conventional leveling and GPS measurement. These deformation monitoring technologies are all point-based, and rely heavily on the stability of reference points, and cannot obtain a wide range of overall deformation. The new synthetic aperture radar interferome...
