Inorganic curing rapid filling material for local site of mine and preparation method of inorganic curing rapid filling material
The invention provides a mine local place inorganic curing filling material which comprises the following components in parts by mass: 10-40 parts of cement, 5-30 parts of coal ash with the coal content of 1-15% and the strength of 40-100 MPa, 5-30 parts of coal gangue powder with the carbon content of 15-30%, 5-30 parts of silica fume with the refractoriness of 1000-3000 DEG C, the particle size of 0.1-0.3 micron and the bulk density of 1000-2000 kg/m < 3 >, 0.01-10 parts of polypropylene fiber with the filament number of 1-2.2 dtex and the fiber length of 5-50 mm, and 0.5-20 parts of a coagulant. 0.5-20 parts of a composite foaming agent and 30-70 parts of water. The filling material disclosed by the invention is good in stability, adjustable in slurry density, adjustable in setting time, strong in fluidity, not easy to precipitate to block a pipeline, is of a foam porous structure, has relatively good crack resistance, toughness and impermeability, and can be relatively well adapted to a complex environment.
本发明提供一种矿井局部地点无机固化充填材料，按质量份数计包括以下成分：水泥10～40份，含煤量1～15％，强度40～100MPa的粉煤灰5～30份，含碳量15～30％的煤矸石粉5～30份，耐火度1000～3000℃，粒径为0.1～0.3微米，堆积密度为1000～2000kg/m3的硅灰5～30份，单丝纤度1～2.2dtex，纤维长度为5～50mm的聚丙烯纤维0.01～10份，促凝剂0.5～20份，复合发泡剂0.5～20份，水30～70份。本发明充填材料稳定性好，浆体密度可调，凝结时间可调，流动性强，不易沉淀堵塞管道，是泡沫多孔结构，同时具有较好的抗裂性能、韧性及抗渗性，能够较好的适应复杂环境。
