Research on Perimeter Rock Support Technology of Composite Roof Slab Roadway in Deep Mining
In order to study the perimeter rock support technology of deep mining composite roof roadway,taking the 260303 track roadway in Huoshaopu Mine as the engineering background,analyzing the reasons for the damage of composite roof roadway,and proposing the perimeter rock support technology scheme of deep mining composite roof roadway.The results show that:by optimizing the section form of joint anchor cable-long and short anchor coupling support multi-stage perimeter rock support program,can improve the section bearing strength and the joint support of anchor cable,field monitoring of the roof sinking amount is only 48 mm,the two gangs move in the amount of 34 mm,indicating that the effect of perimeter rock control is better,and can ensure the safety of the working face production.
