煤层自燃防治技术体系的建立与应用

Coal seam spontaneous combustion prevention and control technology system establishment and Application

根据特厚煤层综放开采工作面自燃特点,得出了特厚煤层综放开采工作面采空区煤层的自燃危险区域,并确定了"防控结合、重在预防"的防火指导原则,建立了以"预测预报技术、综合防控技术、特殊区域防火技术"相结合的煤层自燃综合防治技术体系,保障了工作面的安全生产。

According to the characteristics of spontaneous combustion at the fully mechanized top-coal caving face of the thick coal seam,the hazard zone of spontaneous combustion in the gob was obtained,and a governing principle of fire prevention in the first place and integrating prevention with extinguishment was determined,the comprehensive technologies of prevention and extinguishment for coal spontaneous combustion which included the fire prediction technology,the fire preventing and controlling technology,the fire preventing in special areas were established.By practiced and applied,it ensured the safety in production of the face in coalmine.
