Abstract:
      The upward horizontal layered filling method is suitable for mining ore bodies with various angles and various thicknesses. It has been widely used in the mining field. However, the determination of the safe span of the mine has always been a difficulty in mining design. Combining Mathews stability diagram method and numerical calculation method, the maximum safety span of the mine through Mathews stability diagram method was firstly determined in this paper, and then simulation analysis by numerical software was carried out to determine the stability of the mine, thus a reasonable span of the mine was obtained, which provided a basis for determining the span of the mine by the horizontal stratified filling method.
