中文摘要: 上向水平分层充填法适用于各种倾斜角度以及各种厚度的矿体开采,在矿山领域得到广泛应用,然而该方法矿房安全跨度的确定一直是矿山开采设计的难题。结合Mathews稳定图法和数值计算法,先通过Mathews稳定图法确定矿房最大安全跨度,然后通过数值软件进行模拟分析,确定矿房稳定性,从而得出矿房的合理跨度,为上向水平分层充填法矿房跨度的确定提供依据。
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.
