@akash kumar please watch my previous uploaded video for powder factor for Opencast mines with this link kzbin.info/www/bejne/b2rOXqiEYtWBqLc first see powder factor has been asked in KG/TN KG - KG for explosive TN - for production or rock 1) calculate weight of explosive = 3.14× (75/1000)×(75/1000)×(13-4)×800 = 127.17 kg radius 150/2= 75mm, in meter = 75/1000 2) production of rock on blasting = burden×spacing×height of face× spec. gravity = 3×4×12×2.5(in tonne) = 360 tonne now put in formula = kg/tn (in which pf has been asked) = 127.17/360 = 0.353
