UNIT3 A-F仓、UNIT4 A-E仓由卸料小车定位在仓上配仓，UNIT4 F仓由小车直通实施配仓。正常情况下，同一时间，一台机组只能由一台卸料小车配仓；
During the reclaiming process and distributing process, the unloading trolley shall carry out bunkering operation to discharge bunker coal into the main workshop silo. When the processes stop, the material on belt conveyor between wharf and stockyard should be transported to stockyard (see distributing process for details) and the material on belt conveyor between stockyard and silo should be transported to silo;
The bunkering of UNIT3 A-F bunker, UNIT4 A-E bunker shall be finished by unloading trolleys located on them and the bunkering of UNIT4 F bunker shall be finished by unloading trolley directly. Usually, the bunkering of one unit should be done by only one trolley at the same time;
In normal circumstances, the F bunker of every unit is taken as standby bunker (Bypass). The standby bunker will not be adjusted but for coal mill overhauling. However, any bunker may be set as standby bunker in program-controlled system. There should be 1-4 standby bunkers. Each consecutive non-standby-bunker group is defined as a bunker group and there should be 1-5 working bunkers in every bunker group. Every bunker’s excess volume (EV) is defined as the volume difference between the bunker’s current material level and HL corresponding material level. The bunker group EV is defined as the total sum of every bunker’s excess volume (EV) of the group;
For one unit, we only consider the automatic bunkering is possible for 3 standby bunkers. As for 4 standby bunkers, there would be only 2 usable bunkers. This is the most unfavorable condition. In this harsh environment, only manual bunkering should be considered;
No coal unloading for standby bunkers and their excess volumes are not included in EV. When unloading trolley across standby bunkers or units, it should be ensured that there is no coal on BC10 (CV810A/CV810B) belt conveyor (when bucket wheel reclaimer stops reclaiming or process stops, left adequate no material section on BC10. This needs to be confirmed by communication between control room operators and bucket wheel reclaimer driver or by industrial television monitoring and other auxiliary tools, and make delayed time processing in the program, see 10 across bunker program);
During program-controlled operation, the bunkering may not in the preset order in residual coal distributing program and the program determines which bunker to go;
As the process starts, unloading trolley moves immediately to the started target bunker, make EV, HL2, HHL judge to the current bunker after moving in place. Hereafter, in bunker shifting in every normal procedure, always make EV, HL2, HHL judge after moving in place; however, for unloading trolley in residual coal distributing program, only make HL2, HHL judge after moving in place.
