Research on the Setting Width and Support Technology of Small Coal Pillars in Driving Roadway Along Goaf in Shallow Buried Coal Seams
In order to study the setting width of small coal pillars and support technology for roadway along goaf in shallow buried coal seam sections,the small coal pillars of driving roadway along goaf in the 15103 working face of Weizizhen Mine are taken as the research object.Through theoretical calculation and numerical simulation analysis,the reasonable width of the small coal pillar is determined to be 7 m.A support scheme is proposed,which used anchor rod + anchor cable combined support during excavation period and advanced support to strengthen support during mining period.This scheme has a relatively good control effect on the deformation of the roadway along goaf in the 15103 working face and achieves significant benefits.
