摘要
阐述了高水胶凝剂混合粉煤灰灌注技术的优点,介绍了灌注充填工艺使用设备情况、灌注适用地点、原料配比、灌注工艺要求、操作流程及注意事项。以大同煤矿集团公司同安煤矿利用高水胶凝剂混合粉煤灰灌注技术成功封堵小窑火区,及高水胶凝剂混合粉煤灰灌注技术在永定庄煤矿985大巷维护中的应用为例,说明粉煤灰胶凝剂具有良好的防水性能及防火效果。
The advantages of pouring with high water gelling agent mixed with coal ash were described.The utilization of facilities for pouring and filling,proper sites for pouring,raw mate-rial ratio,requirements for pouring,operation procedures and matters need attention were intro-duced.The application of pouring with high-water gelling agent mixed with coal ash to successful sealing the fire area of small mine pit in Tong＇an Coal Mine of Datong Coal Mine Group and the application of pouring with high-water gelling agent mixed with coal ash to maintenance of No. 985 main roadway of Yongdingzhuang Coal Mine showed that coal ash gelling agent possessses good water proof property and fire prevention effect.
