What is the mine pressure? For a long time in the past, we used to call the pressure of surrounding rock due to deformation and falling rock on the support as mine pressure (mine pressure for short), which is the concept of traditional "narrow mine pressure", is incomplete, and is only a small part of mine pressure. With the continuous deepening and development of mining rock mechanics research, people have gradually realized that, between the perimeter rock roof and anchor network cable support, roof and stent is not the relationship between the load and support configuration, but a closely linked interaction, mutual influence and common bearing structural relationships (such as anchor network cable support, trellis beam support, comprehensive mining support, monolithic hydraulic pillars and other support structures development and application).
