High-mixing-amount solid waste grouting material for mine limestone aquifer transformation and method
The invention discloses a large-mixing-amount solid waste grouting material for mine limestone aquifer transformation and a method. The large-mixing-amount solid waste grouting material is prepared from, by mass, 30-60 parts of coal ash, 30-60 parts of coal gangue, 0-40 parts of slag ash, 0-30 parts of cement and 0-5 parts of sodium hydroxide. The method includes the steps of: performing grouting: mixing fly ash, coal gangue, slag ash, cement and sodium hydroxide according to a preset proportion, adding a certain amount of water, performing mixing, conducting stirring in a stirrer, and carrying out standing for molding; conducting drilling operation on the mine limestone aquifer through drilling equipment, conducting grouting after drilling is conducted to the bottom at a time, after grouting of the section at the bottommost end is completed, blocking the grouted section by a grouting stopping plug, and then starting a next section of grouting; and after drilling and grouting are completed, blocking cracks in a grouting mode. The material disclosed by the invention fully utilizes industrial wastes, can reduce the influence on the environment, is low in cost and easy to prepare, and has the beneficial effects of fully utilizing the existing solid wastes, saving energy, protecting the social environment and the like.
本发明公开了一种用于矿井灰岩含水层改造的大掺量固废注浆材料及方法，包括如下质量份数的原料配方：粉煤灰30‑60份，煤矸石30‑60份，炉渣灰0‑40份，水泥0‑30份和氢氧化钠0‑5份。注浆步骤：将粉煤灰，煤矸石，炉渣灰和水泥和氢氧化钠按照预定比例混合，并加入一定量的水混合并置于搅拌机中搅拌，静置成型；采用钻孔设备对矿井灰岩含水层进行钻孔作业，一次性钻孔到底然后进行注浆，最底端的一段注浆完成后，采用止浆塞将注浆的一段堵住，再开始注浆下一段；钻孔注浆完成后，采用注浆的方式封堵裂隙。本发明材料充分利用了工业废弃物，能够减少对环境的影响，成本低廉，易于制备，具有充分利用现有固废、节约能源、保护社会环境等有益效果。
