中文摘要: 井下采空区利用细颗粒尾砂充填,细颗粒尾砂往往在充填体表面形成一层很薄的细泥层,细泥隔水层阻止了充填体表面上方的澄清水往下渗透,影响了充填体的质量。通过充填尾砂细颗粒在井下采空区的沉降模型,以及其在充填体表面形成细泥隔水层的机理的研究,通过试验研究,利用絮凝剂可以抑制充填体表面细泥隔水层的形成,不同的絮凝剂有不同的效果,从经济和效果上考虑,选用明矾作为絮凝剂较为有利。
Abstract:Underground goaf use fine-grained tailings filling, fine-grained tailings tend to form a thin layer of fine mud on the surface of backfill, fine mud impermeable layer prevents the clarified water above the surface of the filling penetration down, affecting the quality of filling body. Backfilling materials by fine grain filling in the underground mine-out area and its filling body surface subsidence model study of the mechanism of fine clay impermeable layer. Through the experimental study, use of flocculants can inhibit the filling body surface formation of fine clay aquiclude. Different flocculants have different effect. From the consideration on the economy and the effect, choose alum as flocculant is more advantageous.
