摘　　要：通过分析研究近距离煤层群正压通风矿井自然发火的规律,提出对于近距离煤层群正压通风矿井煤自燃的治理,宜使用以注氮为主,堵漏、灌浆、加快回采速度为辅的综合防灭火技术。矿井的应用实践证明,这种技术能有效控制上部采空区的遗煤自燃,取得有效的火灾防治效果。The prevention method of mine spontaneous combustion with positive pressure ventilation in contiguous coal seam group was put forward according analysis of mine spontaneous combustion law with positive pressure ventilation in contiguous coal seam group, nitrogen injection was the main prevention method, and lading stoppage, injection and accelerate mining speed and so on were the sub-sidiary methods. The practical showed that coal spontaneous combustion of upper goaf could be controlled effectively, and fire prevention and control was effectively.
