    Feasibility Analysis of Using Special Filling Roadway to Carry on Top Coal Caving Backfill Mining

    • Combined with the existing top-coal caving technology and based on analyzing the existing complex technical equipment systems, poor effect of reducing the surface subsidence and many safety risks, it is demonstrated from a technical point of view that using the new technology can avoid the excessive pressure in roof, spontaneous combustion and high concentration of gas and dust in the underground, and two formulas were put forward from an economic point of view after introducing the arrangement of the roadway.
