In view of the difficulty of calculating the temperature field of surrounding rock and the heat dissipation of surrounding rock in the working face, the differential equations of thermal conduction under dynamic coordinates and the finite element solving method and calculation formula of this equation are studied. The calculation program is compiled by FORTRAN language and the example calculation . The example proves that the method can calculate the heat dissipation of the surrounding rock in mining face quickly and accurately.
