The document provides an overview of the direct rope haulage system used in mining for transporting minerals. It details the types of systems, specifically single drum and double drum haulage, along with their advantages, disadvantages, applicable conditions, and safety devices. The single drum system is simpler but has higher power demands, while the double drum system offers higher output but requires wider roads and efficient braking.

3. ❖ DIRECT ROPE HAULAGE
SYSTEM
•Direct rope haulage system used in mines for hauling
minerals.
•It is the simplest system of hauling minerals from
mines

o Direct rope haulage types.
oDirect rope haulage diagram.
o Safety devices.
oSingle drum direct rope haulage.
o Double drum direct rope haulage.
o Applicablity of direct rope haulage.
oAddvatage and Disaddvantage.

6. ❖TYPES OF ROPE HAULAGE
•Single drum direct rope haulage.
•Double drum direct rope haulage.

7. ❖ SINGLE DRUM DIRECT
ROPE HAULAGE
• This is the simplest system of rope haulage.
• It consists of one track, one rope & one drum which are
connected to a motor through gear.
• One end of the rope is connected with the train of tubs on
the track & another end of rope is connected to the drume.

8. ❖SINGLE DRUM DIRECT ROPE HAULGA

9. ❖SINGLE DRUM DIRECT ROPE
HAULAGE
•Haulage way to gravity gradient 1 in 10.
•Haulage engine situated in tope of gradient.
•Power not required when tubs are move to downword.
•The angle of main track and branch track most efficient
is 40°.

10. ❖ APPLICABLE CONDITION
• It consist inclination working.
• Deep area required for installation.
• It can be work as main haulage.

11. ❖ IMPORTANT POINTS
➢Gradient 1 in 10.
➢Speed 8 - 10 km /h
➢Safety Device = backstay , stop block , drop warwick ,
buffer jazz , tube reraile , combined stope block , run away
switch and man hole.
➢Motor = slip ring motor used with drum controller.
➢Break = caliper break
➢Track gauge = 0.6.

12. ❖ SINGLE DRUM DIRECT ROPE
ADDVANTAGE HAULAGE
➢Layout and operation is simple
➢High speed
➢Single track required
➢It consist long distance

13. ❖ SINGLE DRUM DIRECT ROPE
DISADDVANTAGE
➢High peak power dimand.
➢Strong break system needed.
➢Not use for less gradient.
➢High supervision needed.
➢High speed maintenance required.

14. ❖ DOUBLE DRUM DIRECT ROPE
HAULAGE
• This is the simplest system of rope haulahe . It consist of
two rope , two drum , two track but only driving motar .
One end of each rope is connected with two drem &
another end of the rope is connected with the set of tubs .
• In such way that when one set of tub is at incline top. The
another set is at incline bottom.

15. DOUBLE DRUM DIRECT ROPE
HAULAGE
• The two drum are connected with each other. When the
drume rotates, the rope coil on the drum & uncoils from
another drum
• It can be used if inclination is more than 1 in 12.
• The speed of the system is 8 to 12 km/h.

16. ❖DOUBLE DRUM DIRECT ROPE
HAULAGE

17. ❖DOUBLE DRUM DIRECT ROPE
HAULAGE

18. ❖ DOUBLE DRUM DIRECT ROPE
HAULAGE ADDVANTAGE
➢Higher output.
➢Less power demand.
➢Branched road can also be served , if greadient is
suitable.

19. ❖ DOUBLE DRUM DIRECT ROPE
HAULAGE DISADDVANTAGE
➢Wider roads required .
➢Efficient breaking system required for downward journey .
➢High speed haulage demands more maintenance of track
.
➢Cannot be used for less incline roadways .
➢A derailment is associated with heavy damages .
➢Due to hige speed more dust , more wear & tear .
