Large-flow micro-expansion quick-setting tunnel blast hole blocking material and preparation method thereof
The invention discloses a large-flow micro-expansion quick-setting tunnel blast hole blocking material which is prepared by the following steps: mixing sand, expansive cement, an expanding agent and an accelerator in proportion, then mixing with water, a water reducing agent and high-molecular water-absorbent resin to obtain a mortar material, then filling a blast hole with the mortar material, and standing to obtain the blast hole blocking material. Compared with the prior art, the prepared blast hole blocking material has the advantages that the blasting effect is improved, the energy utilization rate of explosives is increased, and the usage amount of the explosives is reduced.
本发明公开了一种大流动微膨胀快凝隧道炮孔堵塞材料，该炮孔堵塞材料通将砂、膨胀水泥、膨胀剂和速凝剂按比例混合后，再与水、减水剂和高分子吸水树脂混合，得到砂浆料，接着将砂浆料填入炮孔中，静置得到炮孔堵塞材料。与现有技术相比，本发明制备的炮孔堵塞材料具有改善爆破效果，提高炸药能量利用率，减少炸药使用量等优点。
