Evolution Mechanism of Interconnected Vertical Fractures in the Overburden of Longwall Coal Mining
Whether a tensile failure fracture will penetrate a stratum is difficult to ascertain at present. In view of this, the method of similar simulation and field verification are used to carry out a systematic study. Similar simulations show that tensile failure fractures will penetrate the layered stra...
