【Abstract】 This paper analyses and calculates the artificial freezing procedure of stratum using finite element method with two dimensions. The simple and effective method is specially presented for the calculation of release of the latent heat. The calculating results are basically identical with eleven constructing practices of Huai-Nan mine-concession. The way presented in the paper is generally suitable for the problems of non-linear heat conduction with two dimensions containing the latent heat.更多还原
