Surrounding Rock Control Technology of Strong Dynamic Pressure Composite Roof Roadways
The dynamic pressure in the deep part of the coal mine is strong,and the surrounding rock of the mining roadway with composite roof is severely deformed,with a potential risk of roof collapse.In order to solve the problem of surrounding rock control in strong dynamic pressure composite roof roadways,this paper took 2329 working face as the research object.By optimizing the support plan,increasing the support strength of the roof and two sides of the roadway surrounding rock,it had played a good control role in the deformation of the composite roof surrounding rock.After on-site practice verification,this improved plan has good applicability.
