摘要
为提高煤层注水封孔材料的封孔性能,研发出一种新型封孔材料,并在实验室进行不同配比试验,最后优化出一种微膨胀、较高抗压强度、密封效果好、成本低的新型封孔材料,该材料配置简单,操作方便,推广应用前景广阔。
In order to improve the sealing performances of the sealing material for coal seam water infusion, a new sealing material was developed . Different ratio tests were carried out in the laboratory and, finally, optimize a micro expansion seal, high compressive strength, good effect and low cost of a new sealing material, the material has simple configuration, convenient operation, wide application prospect.
