Calculation of Temperature Distribution of Surrounding Rock and Cooled Zone Radius by Semi-explicit Difference Method

A mathematical model calculating the temperature distribution of the surrounding rock and cooled zone radius, and a semi-explicit difference scheme that was better than general difference scheme was established. A program is coded to calculating the temperature distribution of the surrounding rock and cooled zone radius. The temperature distribution of the surrounding rock was obtained. The correctness and precision of the semi-explicit difference scheme was proved through contrast between Solution value and measurement value.
