基于淮南矿业集团多年来的科研实践和现有防灭火技术及装备的现场应用情况,提出高瓦斯煤层群煤层防灭火工程解决方案。以高瓦斯煤层工作面自燃的特点,自燃特性参数实验测试和现场观测为基础,加强煤层火灾的早期预测和预报,建立完善的矿井防灭火系统,形成了以堵漏、灌浆、均压、注氮和注胶为主要防灭火手段的高瓦斯煤层群煤层自燃综合防灭火体系。 Based on the scientific research practice of Huainan Mining Group over the years and on-site application of fire prevention technology and equipment, the solution of fire prevention and extinguishment of coal seam with high gas coal seam group was put forward. Based on the characteristics of spontaneous combustion of spontaneous combustion in coalface, the experimental and field observations of spontaneous combustion parameters, the early prediction and prediction of coal seam fires are strengthened and a perfect mine fire extinguishing system is established. Nitrogen and plastic injection as the main means of fire prevention and control of high gas coal seam spontaneous combustion coal fire prevention and control system.
