摘要

针对沿空留巷高水材料充填体特性与力学作用机理不够完善等问题,根据凌志达煤矿15210工作面具体地质条件,采用理论分析、力学计算结合现场实测等手段,建立了高水材料充填体切顶力学模型,分析了其控制巷道稳定的力学机理,计算得到了沿空留巷充填体切顶阻力为2265kN/m,确定了充填体具体参数。
        In this paper, the problems of imperfect filling characteristics and mechanical mechanism of high-water material in gob-side retaining roadway are discussed. According to the geological conditions of the15210 working face in Lingzhida Coal Mine, the mechanical model of cutting roof of filling body with high-water material is established by means of theoretical analysis, mechanical calculation and field measurement, and the mechanical mechanism of controlling roadway stability is analyzed. The filling body cutting along gob-side retaining roadway was calculated and obtained. The top resistance is 2265 kN/m, and the specific parameters of filling body are determined.
