High-rate quick-setting mining hole sealing material and use method thereof
The invention discloses a high-rate quick-setting mining hole sealing material and a using method thereof, and belongs to mining hole sealing materials. The hole sealing material is prepared from thefollowing raw materials in percentage by mass: 10%-30% of quick-setting powder, 60%-80% of Portland cement, 1%-6% of bentonite, 0.3%-0.5% of sodium chloride, 0.1%-0.3% of sodium aluminate, 3%-8% of quick lime, 0.05%-0.2% of a water reducing agent and 0.05%-0.2% of an active agent through even stirring according to the mass ratio of 1: 1.6-2. The hole sealing material is high in multiplying power and short in setting time, the expansion multiplying power ranges from 10% to 100%, the final setting time is shorter than 120 min, the compressive strength and the setting time are not affected whilethe multiplying power is improved, the strength and the setting time of gas extraction are met, and the long-term effect of hole sealing is guaranteed. Due to the high-expansion property of the hole sealing material, the pipe wall is filled with the hole sealing material, gas leakage caused by pores is avoided, the safety performance is improved, materials are saved for extraction pipes with the same length, and the gas extraction cost is reduced. The hole sealing material has the advantages of low price, no toxicity, no pollution, high hole sealing efficiency, favorable flowability and favorable plasticity.
一种高倍率速凝型矿用封孔材料及使用方法，属于矿用封孔材料。该封孔材料按照质量百分比包含以下原料：速凝粉10～30％，硅酸盐水泥60～80％，膨润土1～6％，氯化钠0.3～0.5％，铝酸钠0.1～0.3％，生石灰3～8％，减水剂0.05～0.2％，活性剂0.05～0.2％，使用时将水与封孔材料按照质量比为1：1.6～2搅拌均匀即可。封孔材料倍率高，凝结时间短，膨胀倍率在10％～100％，终凝时间小于120min，在倍率提高的同时抗压强度及凝结时间不受影响，满足瓦斯抽采的强度及凝结时间，保证封孔的长期效果。封孔材料的高倍膨胀性使封孔材料充满管壁，不会产生孔隙造成瓦斯的泄露，提高安全性能，对于相同长度的抽采管节约用料，降低瓦斯抽采成本。价格低廉，无毒、无污染、封孔效率高，具有良好的流动性及可塑性。
