【摘要】 应用红外探测技术对煤巷近距离(<10m)自燃火源位置进行了深入的研究与实践,提出了探测方法.根据巷道壁面的红外探测能量场分布,建立了煤巷煤层自燃高温点的热传导方程,提出了煤巷近距离煤层自燃高温点的反演算法,并用最小能量准则和有限失拟准则解决了反演过程中解的不适定问题,确定了自燃火源的深度、范围和温度.更多还原

【Abstract】 The paper carries out elaborate investigation and practice on closerange coal inflammation position at coalroads using the method of infrared detecting technology, meanwhile, brings forward detecting techniques. According to the infrared detecting energy field distribution of laneways wall face, heart conduction equations of hyperthermic firing points are established, in the same time, the inverse heat conduction arithmetics of closerange hyperthermic firing points are also put forward. Moreover, the criterions of minimum energy and finite vector fitting are applied to puzzle out the unaccommodated problem of solution during inversion and determine the depth, scope, temperature of coal spontaneous combustion.更多还原
