双鸭山东荣三矿2 0 0 3年发生火灾,开始应用注水、注惰、注灭火剂等方法,均未控制住火势。后来,通过该矿现有的灌浆系统,形成复合胶体管网式防灭火系统,利用该系统向火区周围密闭墙内大量压注粉煤灰复合胶体,堵塞了向火区漏风的通道,扑灭了大范围火源。接着启开火区下部的运输上山,从运输上山向火区打钻,由钻孔直接向火区注复合胶体,彻底扑灭了火灾,保障了矿井安全生产。实践表明,复合胶体管网式防灭火技术是一种快速高效的防灭火技术,适应大面积煤层火灾的防治要求。
In 2003, a fire broke out in Dongrong No.3 Mine, Shuangyashan, and fire, water injection, injection of inert gas and fire extinguishing agent injection were not started. Later, through the existing grouting system in the mine, a composite colloid pipe network type fire prevention and extinguishing system was formed, a large amount of fly ash composite colloid was pressed into the confined wall around the fire area by the system, and the air leakage path to the fire area was blocked, A wide range of sources of ignition. Then open the lower part of the transportation area of the fire up the mountain, from the transport up the mountain hit the fire zone drilling, direct injection from the hole to the fire zone compound, completely extinguished the fire to protect the mine safety in production. Practice shows that composite gel network fire prevention and control technology is a fast and efficient fire prevention technology to adapt to large-scale coal seam fire prevention and control requirements.
