Analysis and Application on Controlling Thick Hard Roof Caving with Deep-Hole Position Presplitting Blasting
For the thick hard roof (THR) in Datong mining area, mining operations often led to large-scale hanging-roof and frequent and strong strata behavior, threatening mining safety seriously. Based on the instability mechanism, the fracture model for THR was established, including rock blocks articulatio...
