从理论上对采空区三带划分进行量化分析，对氧化升温带和氧化自燃带的概念进行了区分，并分析了动态情况下采空区氧化自燃区域的确定方法，提出了最小安全推进速度的概念及其计算方法，为采空区火灾预测预报提供了新的思路和方法。
In this paper, we quantitatively analyze the division of the three zones in the goaf, and distinguish the concepts of the oxidation temperature increase zone and the oxidation spontaneous combustion zone. The method to determine the spontaneous combustion zone in the goaf under dynamic conditions is analyzed. The minimum safety promotion speed The concept and calculation method provide a new idea and method for fire forecasting of goaf.
