Research on Mechanical Characteristics and Supporting Parameters of Advanced Support of Integrated Excavation Roadway
In order to better improve the efficiency of mine tunnel excavation and adapt to the special situation of uneven tunnel surface,static simulation was conducted on the advanced support,and the non equal strength support effect of the advanced support group was evaluated.Through comparative analysis of experiments,the following conclusion can be drawn:Compared with the maximum displacement of equal strength combined support,the maximum displacement of the roof under non equal strength combined support is reduced by about 5%.It can be seen that the non equal strength combined support method has played a certain role in maintaining the stability of the roof.
