Characteristics of stratum movement induced by downward longwall mining activities in middle-distance multi-seam

With the development of mining depth, multi-seam mining activities is becoming more and more frequent. Correspondingly, the study on stratum movement characteristics induced by multi-seam mining activities is of great significance for preventing water inrush disaster and forecasting support pressure, surface deformation, gas drainage and other mining problems. According to the interaction among the caved zone, the fractured zone and the...
