gradually. Although the local temperature only increased by 2–3°C, the overall temperature
curve was rising. There is a tendency to get angry. In the front part of the curve throughout
the day, the high temperature point gradually shifts from 58 meters to 42 meters.
We can also deduce the possible distribution of “three zones” in coal mines according to
the change of temperature. We can magnify the temperature data from 10 meters to 60 meters
further. Some interesting conclusions can be found. Figure  4, the high temperature point
gradually shifts from 58 meters to 42 meters.
