摘要:
煤矿井下由于煤炭自燃引发的火灾是煤矿生产过程中一大突出灾害，一旦发生火灾将严重影响煤矿的正常生产，这不仅威胁着井下人员 的生命安全，还会给国家带来巨大的经济损失。由于矿井下隐蔽火源是引发火灾的重大因素之一，所以要更好的解决煤炭自燃而引发火灾的问 题，重中之重就是对煤炭自燃隐蔽火源位置的确定。只有准确的确定了火源的位置，才能有的放矢地进行灭火。本文结合煤矿井下煤炭自燃发 火的特点，建立数学模型，把煤矿井下隐蔽火源位置确定问题归纳为热传导方程的寻源反问题，利用离散正则化方法求解热传导方程，克服了 反演问题的不适定性，并应用matlab进行了反演数值模拟，验证了利用离散正则化反演方法的实用性，为防火、灭火采取措施提供了依据，在 理论上也具有一定的研究与应用价值。
Abstract:
The fires which caused by coal spontaneous combustion is one of prominent disasters in coal mine underground production process, once a fire disasters happen ,it will seriously affect the normal production, it not only threatens the life safety of coal mine personnel, but also bring a nation huge economic losses. Because of concealed ignition is major factor to cause fire, so if we want to better to solve and fires problem which caused by coal spontaneous combustion, the most important thing is determine position of concealed fire which cause the coal spontaneous combustion. Only an accurate determination of the fire position, have something to aim to put out the fire. This article combine coal self-ignition characteristics underground coal mine, establish the mathematical model, inductive the problem of determine the coal mine underground concealed fire position to the inverse problem of the heat conduction equations source, using discrete regularization method to solve the heat conduction equations, overcoming the discomfort of inverse problem, and the application of matlab to inverse numerical simulation, and verified using of discrete regularization inversion method, provide the basis for take measures to prevention and extinguishing, it also has a certain research and application value in theory.
