基于新型胶体泥浆材料良好的堵漏、降温、阻化、固结水等性能,采用钻孔压注方式,将其注入防灭火区域,利用材料胶凝后包裹煤体的特性,有效克服了传统灌浆材料浆水的泄漏流失问题。实践证明,新型胶体泥浆材料具有良好的防灭火性能,其在近1 000℃的明火中不会迅速汽化,且在井下环境湿度90%,温度28℃条件下,防灭火性能保持13个月以上。
Based on the good performance of the new colloidal mud material, such as plugging, cooling, resistance-deteriorating and water consolidation, it is injected into the fire prevention and extinguishing area by means of injection and injection of drilling holes. By utilizing the characteristics of the wrapped coal after gelation, the traditional Leakage loss of grout slurry. Practice has proved that the new colloidal mud material has good fire extinguishing performance, it will not be rapidly vaporized in nearly 1 000 ℃ open flame, and in the downhole humidity 90%, the temperature 28 ℃ under the conditions of fire-fighting performance to maintain more than 13 months .
