Research on Deformation Controlling Technology of the Narrow Pillar of Insular Coalface Roadway Driving along next Goaf

Abstract:

Through surrounding rock controlling mechanism analysis of roadway driving along next goaf, the corresponding technical measures are put forward, and a new combined support scheme of anchor-girder-net support is designed. The results show that the roadway is located under the cantilever beam, which can be better to avoid roadway damage from rock fracture and bending and sinking in caving zone. Cooperated with twice times grouting to the coal pillar and roof, the new combined support scheme had effectively controlled the roof structure destruction again. Field application results indicate that the new support scheme effect is remarkable, the deformation of roadway had been reduced by 55% to 60%, and deformation of surrounding rock had been significantly controlled, which can provide a reference for similar mine area.
