Study on Reasonable Support Form of Goaf Excavation Roadway in Deep Inclined Coal Seam
In order to solve the problem of changing the supporting parameters for many times in the roadway driving process of deep inclined coal seam, this paper combined with the actual situation of Fucheng Coal mine and the roadway deformation of 1903N return wind roadway was relatively serious in the roadway driving process due to the influence of 1902 mining. The form of support is difficult and ordinary forms of support cannot play an effective role. The problems of roadway deformation and bolt support in the roadway driving along goaf under the strong influence of mining were comprehensively analyzed. Finally, extended bolt + anchor cable grout support can effectively reduce the amount of roadway deformation, which effectively strengthens the stability of inclined coal seam roadway driving and provides a guarantee for the safety of coal mine production.
