自燃煤层综放开采防灭火技术研究

针对综放开采煤层中容易自燃的问题，研究了防灭火技术，采用预防性灌浆、罗克休泡沫防火技术、氮气防灭火措施和建立自燃监测体系的技术手段，且要考虑到通风、地质、产量等因素对煤层自燃的影响，积极采取针对性的预防措施，在保证人员安全的同时提升企业效益。

Spontaneous Combustion of Coal Seam Fire Prevention in Full-mechanized Caving Mining Technology

In view of the problems in fuU-mechanized caving mining coal seam spontaneous combustion, ~rre prevention technology was studied, and the preventive grouting, foam fire protection technology, nitrogen fire prevention measures and the establishment of monitoring system of spontaneous combustion technology were adopted. Ventilation, geological and production factors on the coal seam spontaneous combustion affecting actively taking corresponding prevention measures were taken into account to promote personnel safety and enterprise benefit.
