in this video i've discussed about the STOPING method i.e. BREAST STOPING method with interactive animation in metal mine.
HOPE THIS VIDEO WILL BE HELPFUL TO YOU!!!

BREAST STOPING:
WHEN THE HOLES ARE DRILLED IN FRONT OF FACE SUCH HOLES ARE KNOWN AS BREAST HOLE.
WHEN A STOPE IS EXTRACTED BY BREAST HOLES THE METHOD OF STOPING IS KNOWN AS BREAST STOPING.
APPLICABILITY:
-ORE BODY REQUIRED STRONG
-BOTH HANGWALL AND FOOTWALL SHOULD BE STRONG.
-INCLINATION - 0 - 30 DEG
-THICKNESS IS NOT MORE THAN 4.5m.
Description :
 The horizontal movement of a vertical face is called breast or
when the holes are drilled in front of face such holes are called
breast holes. When a stope is extracted by breast holes the
method of stoping is called breast stoping.
 In this method 2 levels are driven in the horizontal direction &
serve for haulage way.
 In this method ore is broken by flat or slightly inclined holes
drilled in a vertical or nearly vertical face (breast) of
considerable lateral area, which is being advanced in a nearly
horizontal direction and the work resembles that of advancing
the face of a very wide drift.
 The face is in dip rise direction & mining process along the
strike. Breast is used exclusively in the case of open stopes as
opposed to the overhand & underhand stope which is adopted
with other support systems as well.
 Breast stopping is a low cost, simple method much preferred
for low grade ore deposit where supporting ore pillars may be
left. The ore and the wall rocks should therefore be strong.
The method is best suited deposits of horizontal or mild dip of
thickness of up to 5m, lying a moderate depth.
ADVANTAGES:
-SELECTIVE MINING IS POSSIBLE.
-WORKING IS EASY AS WE WORK ON SOLID GROUND.
-IT IS CHEAP METHOD
-MATERIAL SUPPLY IS DIRECT AND EASY.
-POCKET DEPOSITS CAN BE WORKED.
-LESS ADDITIONAL SUPPORTS ARE USED.
-DRILLING IS EASY.
-SUPERVISION OF WORKER IS EASY AS MAXIMUM WORKERS ARE PUT IN THE STOPE.
DISADVANTAGES:
-NOT SUITABLE FOR HIGH INCLINATION OF ORE BODY
-NOT SUITABLE FOR THICKER THAN 4.5m
-RECOVERY OF ORE IS LESS.
-NOT SUITABLE FOR COSTLY AND RICH MINERAL.
