There is some discussion of the coal mine railways on the Feldbahnforum website; see the Afghanistan Kohlenminen
thread from 20 Okt 2010, 14:29 (you may need to register, and it is auf Deutsch).
The locomotive in this photograph is identified as a BND15. The hopper wagons at the mine are apparently the Czechoslovakian JDV (“unified mining car” design), manufactured by Zelezárny Vítkovicé (Vítkovice iron works).
If I have understood the thread correctly, some BND15 locomotives and also one BND30 were supplied to Afghanistan.
