CUT & FILL stoping / animation / stoping methods / metal mining

in this video i've discussed about the STOPING method i.e. CUT & FILL STOPING method with interactive animation in metal mine.

APPLICABILITY: STEEP TO MILD DIPPING ORE BODIES REASONABLE STRONG ORES. LARGE DEPOSIT WITH REGULAR OR IRREGULAR BOUNDARIES STRONG TO WEAK WALL ROCK LOW TO HIGH GRADE ORES TO PREVENT GROUND SURFACE FROM SUBSIDENCE Description : A slice has a thickness more than 3m. The broken ore is loaded and completely removed from the stope, when one slice of ore has been excavated, the corresponding volume is filled with waste material. The filling serves both as support for the walls and as a floor when the next slice above is mined. The filling material may be waste rock excavated during development crushed and distributed mechanically over the stope area. In modern cut and fill mining the hydraulic filling method is normal practice. The filling material may be sand, crushed rock, boiler plant ash or slag at smelter plants. The filling material mixed with water, is transported into mine and distributed through pipe lines. Preparation : 1. Haulage drift along ore body at the lower main level. 2. Undercut of the stope, usually 5-10m above the haulage drift, 3. Short raises for manwaus and ore passes from haulage drift to undercut. 4. Raises from undercut to the above for transport of filling material and for ventilation. 5. Provision of sufficient water and filling material and arrangement for their storage and transport. 6. Adequate pumping capacity for underground to pump out water overflowing from the filled stope. Development : The ore slices can be drilled in two different ways, with horizontal shot holes or with upward, vertical holes, for drilling light rocks simple wagons are often used. An advantage of up hole drilling method is that large section of the roof can be drilled without interruption and large round can be blasted. A the stope proceeds upwards timbering and filling proceeds on a cyclic basis. Cut & fill mining permit of mechanization of drilling and loading operation. Cut & fill mining has a very broad range of application due to the flexibility good recovery and the possibility of mining rather weak rock condition. ADVANTAGES: -ORE IS REMOVED IMMEDIATELY AFTER BLASTING -THERE ARE NO FIRE HAZARDS AND NO OXIDATION PROBLEM -VENTILATION IS COMFORTABLE BECAUSE OF SMALL AREA OF STOPE -FOR AIR CURRENT. -DILUTION OF ORE IS MINIMUM AS NO SPALLING OF WALL ROCK. -SECONDARY BLASTING CAN BE DONE IN STOPE -THE METHOD PROVIDES PERMANENT SUPPORTS FOR STRUCTURES -MILL TAILING, IF THEY ARE USED FOR FILLING, REDUCE THEIR DISPOSAL PROBLEM ON THE SURFACE. DISADVANTAGES: -IT IS A CYCLIC METHOD -SUITABLE FILLING MATERIAL MAY NOT BE AVAILABLE. -PRODUCTION COST IS MORE DUE TO FILLING OPERATION. affiliate link:- amazon.in elements of mining tech -vol 1-dj deshmukh : https://amzn.to/2EVrzFH elements of mining tech -vol 2 -dj deshmukh : https://amzn.to/2PZm1Aq elements of mining tech -vol 3-dj deshmukh : https://amzn.to/2EVfVuh flipkart- elements of mining tech -vol 1 -dj deshmukh : http://bit.ly/34YdXnI elements of mining tech -vol 2 -dj deshmukh : http://bit.ly/2PXEVHS VIDEO: title video - Video by KML from Pexels end video - Video by Gam Ol from Pexels SEND YOUR QUERIES ON :- facebook:-   / mining_mafia.  . instagram:- https://instagram.com/mining_mafiayt?i...
