Temperature in pyrite tunnels changed extremely compared to temperature out of tunnels, where prisoners got out to empty their wagons. Inside, temperatures varied from 50 to 60 degrees Celsius, whereas winter temperatures hit -20 degrees Celsius outside. In winter, prisoners worked naked inside the tunnels, whereas outside they wore fur coats they stored at the entrance to protect themselves somewhat from the extreme change of temperature. This was the cause that the predominant disease of the camp was the cold. It accompanied prisoners for as long as they were forced to live in that hell.

In the copper area the daily target was also seven wagons. Provided that one shovelful of copper weighed less than that of pyrite, work was somewhat less difficult in these areas. Furthermore, climate conditions in copper tunnels were more stable and there was no great temperature variation as in the pyrite area. According to the same estimate, the quantity a prisoner had to manually load onto the wagons every day to then transport them to the heap was 8,400 kilograms of copper.

The work routine was also the same in the copper area. At the start, they extracted mineral with wagons from the work front where the explosion had occurred, cleaned the inert material, and then reinforced the cleared front, create holes to detonate the explosives for the successive shift.

In the pyrite area the daily rate for each working group was seven wagons. As such, the two carters of the group had to fill seven wagons of mineral.  According to former prisoner Shkëlqim Abazi’s testimony, a wagon would take around 200 shovels of pyrite to fill. A shovelful of pyrite weighed from 18 to 25 kg. According to an average number, one wagon had around 3,600 kg of pyrite.  This estimate would mean that the two carters had to fill seven wagons, or 25,200 kg of mineral per shift, or 12,600 kg of mineral each.  Imagine the daily routine for this enslaving work where one man had to load 12,600 kg of mineral every day!

Beyond the grueling process of this mineral’s extraction, pyrite tunnels were far more dangerous than copper ones. The terrain was highly unstable due to the mineral’s acid sand-like composition, therefore collapses in pyrite tunnels were quite often. Furthermore, the acid environment made work all the harder. Acid drops that dripped ceaselessly in the tunnel not only eroded and burnt the prisoner’s unprotected skin; they also eroded and destroyed the rails on which prisoners had to push their wagons. This added on to the exhausting work: as the wagons had to be pushed for around one kilometer and the same distance back.

Family meetings were done according to a monthly schedule determined by prison command.  Prisoners were entitled to meet their families twice a month for 15 minutes. Furthermore, they could send two letters a month to their families, whereas telegrams and cards were allowed with no limitation. Meetings were always done in the presence of wardens.

The tunnels’ amortization was one of the largest impediments of the prisoners’ work process and often in their testimonies they recalled that the greatest difficulty was raising a wagon when it derailed and fell. The prisoner was forced to raise the wagon on his own using his shoulders and upon restoring it on the rails, he refilled it with the fallen mineral.
