Powder Factor calculation for Surface mine Blast Design

[@l516saikalyan4]

Understood powder factor very well.. Thanks sir

[@doyouknow3265]

Sir iam big fan of you sir good explanation sir thank you very much sir

[@shahrilzaidon2525]

Hi Sir, its a good video, just want ur clarification, why u calculate cross sectional area of drill hole is phi divide by 4 and use 0.2m as a radius?

[@engineeringscience1927]

Sir plz make video on design of ventilation... Numerical problems

[@subratapurohit7605]

Plz make this types of videos sir🙏🙏

[@satindersingh4866]

Hats off to you sir

[@venkatesheerla]

Nice sir

[@SudhirKumar-nt1vj]

Hole volume will be π r square Here Diameter given 200mm, so redius Will be half of Diameter So redius will be 100mm?

[@rakeshnani944]

Sir, i have one doubt, density of explosive*1000 tho caluclate chesthe, required explosive value increases avuthundi kada

[@engineeringscience1927]

Make video on underground blast design and surface blast design in details with all parameters..

[@darshandarshu5353]

Sir plz made video about explosive calculation in open cast mining,horizental n vertical holes in iron ore......

[@subratapurohit7605]

Thank you sir

[@gajulasrinivas6491]

Good morning sir how are you sir iam your 07mng student sir

[@gauravchadha4157]

Would you be able to answer a specific question, If I email it to you ?

[@l516saikalyan4]

Sir, Please make a Video on CMR 2017

[@zoref007]

Thks sir

[@akumaemmanuel9202]

Quantity of explosives is given as Expected tonnage * pf,so making pf a subject you were meant to divide QoE/ExT not the other way round

[@akumaemmanuel9202]

Pf = QoE/ExT

[@rakeshnani944]

Can you explain sir

You forgot to minus your stem height
