Grouting composition for transforming loose aquifer of coal mine and preparation method thereof
The invention discloses a grouting composition for transforming a loose aquifer of a coal mine. The grouting composition comprises a main base material, an auxiliary material and a connecting composition; the main base material comprises cement, fly ash and water; the auxiliary materials comprise an expansion additive, caustic soda and slaked lime; the connecting composition comprises metal filings and crushed fiber materials; the main base material, the auxiliary material and the connecting composition are mixed into slurry with flowability. The preparation method of the grouting composition comprises the following steps: preparing a component A; preparing a component B; preparing a component C; uniformly mixing and stirring the component B and the component C to obtain a component D, preheating, activating the component D by a magnetic field, and adding water to prepare the flowable slurry. According to the grouting composition for transforming the loose aquifer of the coal mine and the preparation method thereof, the preparation process is simple, the efficiency is high, a stable and reliable water-resisting layer can be formed after the prepared grouting liquid is grouted, water in the aquifer is effectively isolated, and cracks of the coal seam roof are effectively blocked.
本发明公开了一种煤矿松散含水层改造用注浆组合物，包括主基料、辅料以及连联组合物；所述主基料包括水泥、粉煤灰以及水；所述辅料包括膨胀添加物、烧碱以及熟石灰；所述连联组合物包括金属屑以及纤维碎料；主基料、辅料以及连联组合物混合成具有流动性浆料。上述注浆组合物的制备方法，包括如下步骤：制备A组分；制备B组分；制备C组分；将B组分与C组分混合搅拌均匀制得D组分，预热并进行磁场活化D组分，加水调配制备流动性的浆料。本发明提供一种煤矿松散含水层改造用注浆组合物及制备方法，制作流程简单，效率高，制成的注浆液注浆后可以形成稳定可靠的隔水层，有效对含水层内水进行隔离以及煤层顶板的裂隙封堵。
