Does the questioner want to ask "What is the schedule for coal feeding at the coal yard of a thermal power plant?" The schedule is during the day, on working days, during low power consumption times, as follows:

1. Coal feeding is usually scheduled during the day because visibility is low at night, which is not conducive to operational safety.

2. Coal feeding time is usually arranged on working days to avoid affecting coal demand during holidays.

3. The coal feeding time usually avoids overlapping with the peak power consumption time of the power plant, so as not to affect the stable operation of the power grid.
