| Abstract: | The mine pressure of deep shaft is intense, so the surrounding rock of gob side roadway is very difficult to control and some narrow coal pillars are often leaved in tunneling process of fully mechanized caving face. By understanding the characteristics of deformation and destruction of surrounding rock of gob side roadways and the interaction mechanism between bolt and surrounding rock, the appropriate bolting theory and technology is selected, which can improve the stability of surrounding rock greatly. |
