Research on the bolt supporting principal of developing entry
【Abstract】 Based on the principle of rock-soil mechanics, the bolt supporting technology of mine roadway were researched, it is pointed out that the roadway’s four corner bolt, the prestressed bolt and the extensible bolt play an important role in keeping road stable; it is also indicated that the walls of roadway safeguarded well is important in keeping road sta- ble, which can make the bolt and surrounding rock load-bearing together; bolt and grount- ing technology can increase anchorage capacity, which is very applicable for soft rock supporting and developing entry.
