采空区自燃“三带”数值模拟研究

Numerical simulation of spontaneous combustion“three zones” in goaf

通过利用有限元法对大同某矿0401采空区自燃"三带"进行数值模拟研究,掌握了许多实际观测中无法或难以确定的有关采空区自燃"三带"分布及变化的定量规律,从而为采空区防灭火技术措施的制定提供了理论依据。

The numerical simulation with finite element method was adopted in 0401 spontaneous combustion goaf three zones in some mine of Datong, the distribution and changing law of goaf spontaneous combustion which cannot confirm in site observation was mastered, providing theoretical data for fire prevention and control in goaf.
