Mining inorganic guniting support material and preparation method thereof
The invention discloses a mining inorganic guniting support material and a preparation method thereof, and relates to the technical field of mining filling and reinforcing materials. The concrete is prepared from the following raw materials in parts by weight: 30 to 40 parts of cement, 15 to 25 parts of slag, 20 to 27 parts of lime, 18 to 24 parts of clay, 5 to 8 parts of reinforced fibers, 2 to 4 parts of an accelerator, 1 to 2 parts of a retarder and 1 to 3 parts of a water reducing agent. The grouting supporting material has good fire resistance and can be stably used in a high-temperature environment under a mine, the grouting supporting material can rapidly complete the solidification process in grouting operation, so that the grouting supporting material forms a firm supporting layer in a short time, the early hardening reaction of the grouting supporting material is promoted by adding the accelerator, the strength development is accelerated, and the service life of the grouting supporting material is prolonged. Therefore, the construction period can be shortened, the downtime of a project is reduced, manpower and material resources are saved, and the construction cost is reduced.
本发明公开了一种矿用无机喷浆支护材料及其制备方法，涉及矿用填充加固材料技术领域，包含有以下重量份的原料：30‑40重量份的水泥、15‑25重量份的矿渣、20‑27重量份的石灰、18‑24重量份的粘土、5‑8重量份的增强纤维、2‑4重量份的速凝剂、1‑2重量份的缓凝剂和1‑3重量份的减水剂。本发明具有较好耐火性能，能够在矿下高温环境中稳定使用，在进行喷浆作业中，喷浆支护材料可以快速完成凝固过程，使其在短时间内形成坚固的支护层，通过速凝剂的添加促进喷浆支护材料的早期硬化反应，加快强度发展，提高支护层的抗压、抗拉强度，从而能够缩短施工周期，减少工程停工时间，节约人力、物力资源，降低施工成本。
