Sir pressure behind the sealed off area kya hoga negative or positive ispe ek video banaye

[@MiningClasses]

Okk i will

[@bivekkumar3681]

आप noise level वाला विडियो फिर से दे, numerical अच्छा से बताया गया था।

[@MiningClasses]

Okk i will make video on that topic

Sir rqd problems ?

[@MiningClasses]

very soon video will be uploaded

[@MiningClasses]

@kidambi sai karthik video on rqd problems is uploaded go ahead and watch the video

[@rohitshrivas146]

Sir numarical me factor 9 hoga.

[@MiningClasses]

please check it once it will be 7 as DBT is above 25 degree

[@kishanmahant3109]

Sir what is a FREE FACE ?

[@MiningClasses]

Free face means where explosive can go in a coal mine bord & pillar mining coal is contact from all three side while blasting the side from you are charging is the free face

[@akashkumar-to3hw]

Hard rock open pit mine B=3 n S=4m Bench h=12m sub driilling=1m collar stemming=4 m hole dia =150m density of rock=2500kg/m3 &density of explosive=800kg/m3 pf? Kg/tn

[@akashkumar-to3hw]

Pls sir reply

[@MiningClasses]

@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
