Guniting material suitable for surface treatment of carboniferous coal mine roadway and preparation method thereof
The invention relates to the technical field of coal mine roadway guniting materials and particularly discloses a guniting material suitable for surface treatment of carboniferous coal mine roadway and preparation method thereof. The guniting material comprises solid raw materials and water, wherein the solid raw materials comprise, by weight, 10 parts of cement, 10-15 parts of river sand, 5-10 parts of fly ash, 12-18 parts of coal cinder and 2-8 parts of short fibers. The preparation method comprises the following steps: stirring and mixing solid raw materials and water according to a certainratio. The guniting material is high in adhesive force, high in strength, resistant to corrosion, not prone to cracking, long in service life and high in flatness, the guniting material is suitable for surface optimization treatment of coal mine roadways and the preparation process is simple, so that the guniting material is suitable for batch production, materials such as coal ash and coal cinder can be effectively utilized, the manufacturing cost is low, and the economic value is high.
本发明涉及煤矿巷道喷浆材料技术领域，具体公开了适用于石炭纪煤矿巷道表面处理的喷浆材料及其制备方法，包括固体原料与水，按重量比计算，固体原料包括10份水泥、10～15份的河沙、5～10份的粉煤灰、12～18份的煤渣和2～8份的短纤维。将固体原料与水按照一定比例进行搅拌混合后，得到了一种附着力强、强度高、耐腐蚀、不易开裂、使用年限久、平整度高喷浆材料，该喷浆材料适用于煤矿巷道的表面优化处理，制备过程简单，适合批量生产，能够有效利用粉煤灰和煤渣等材料，制作成本低廉，经济价值高。
