Experimental and numerical investigation the divergence of horizontal and vertical displacement in longwall mining

Mining companies are looking for higher productivity solutions for low and medium-thickness potash seams. The suitable approach here is high-speed cutting longwall-mining. The extreme excavation process require the more frequency control over stress–strain state of rock’s massif to reach safety of above process. Many specialists propose to use InSAR-technology to control the deformations of rock’s massif surface (Figure 1).
