离散正则化方法在煤矿井下隐蔽火源反演中的应用

矿井煤炭自燃是煤矿五大自然灾害之一，而煤炭自燃隐蔽火源位置的确定是解决煤炭白燃问题的关键。针对矿井隐蔽火源存在的特点，将火源位置的确定问题归结为热传导方程的寻源反问题。在理想状态下，假定火源为线火源，采用离散正则化方法对矿井隐蔽线火源进行反演。反演结果表明：该方法能够准确地反演出火源的特性；通过求解热传导寻源反演的方法是解决矿井隐蔽火源发火特性的有效途径，对矿井防灭火研究具有较高的理论和实际应用价值。

The Application of Discrete Regularization Method in Coal Mine Concealed Fire Inversion

Coal mine spontaneous combustion is one of coal mine five nature disasters.The position determination of coal mine spontaneous combustion concealed fire is the key to combustion question. In view of the characteristics of coal mine concealed fire, sums up the determination question of fire position for determining the unknown source term of heat conductivity equation. Under the perfect condition, supposes fire as line fire, applying discrete regularization method into the inversion of coal mine concealed fire. Result indicates： this method can inverse accurately the characteristic of fire. In a word, it is an efficient path to determine fire characteristic by inversing source of heat conduction. It has high theory and practical application value for the research of coal mine fire prevention and extinguishing.
