SECTION: TUNNEL AND ALLIED WORKS. YEAR: 2010-11 ITEM No: 1
ITEM: Excavation for adit by tunnelling methods in all types of rock including cost of all materials,
machinery, labour, scaling excavated surface, ventilation, lighting, drainage, removing and
hauling the excavated muck outside adit upto specified dump area and all other ancil lary
operations etc., complete with initial lead upto 500 m and all lifts.
DATA:Size of adit assumed ( finished section ) : 4.50 m dia
Shape of adit assumed for excavation : D - shape
Height of adit assumed ( finished section ) : 4.50 m
Pay-line margin assumed : 0.20 m
Diameter of adit upto pay line for excavation : 4.90 m
Distance of dump yard from face : within 500 m
Haulage of excavated muck : By dumpers
Pay line
Minimum excavation line
Excavated profile
TYPICAL CROSS SECTION OF ADIT / TUNNEL
1. Checking alignment and marking hole locations :
Deploy drilling jumbo for 1 hour for marking hole locations.
2. Drilling holes :
Full face method of excavation is assumed.
Area of adit upto pay-line ( 0.5 x 0.7857x 4.9 x 4.9 )+( 4.9 x 2.45 ) : 21.43 sqm
The drilling pattern for excavation of tunnel / adit depends on the size and shape of tunnel, rock
formation, type of explosive and the fragmentation of rock required to suite the type of mucking
equipment. The drilling pattern shall ensure minimum over-break.

TUNNEL AND ALLIED WORKS
Generally, the cut holes and easers will be spaced at 650 to 750 mm grid and the trimmers will
be spaced at 500 to 600 mm apart along the periphery of excavation area.
Considering this, the number of holes for tunnel excavation will be generally in the range of 2.5
to 3 per sqm of cross sectional area upto pay line for small tunnels ( cross sectional area less
than 45 sqm ) and in the range of 2.0 to 2.5 per sqm of cross sectional area for large tunnels.
For rate analysis 2.5 holes per sqm of cross sectional area upto pay line considered for adit.
Number of holes for full face excavation ( 21.43 x 2.5 ) : 54 Nos

Extra drilling considered at 10 percent for inclined cut holes and for any secondary blasting of
large fragments during mucking.
Depth of drill ing for 54 holes ( 54 x 2 x 1.10 ) : 119 m
Average rate of drilling per hour per jack hammer : 5 m
Time for 4 jack hammers with pusher leg for drilling. ( 119 / 4 / 5 ) say : 6 hours

4. Defuming and scaling loose materials:
No machinery other than ventilation fans are required. For defuming adit ventilation fans are
installed in duct system at about 300 m interval and are run for about 1 hour after each blast.
Consider 20 hp fan 1 No. for 1 hour for defuming.
5. Mucking excavated rock :
Quantity of muck to be removed per blast considering 40 % bulkage : 54 cum
Capacity of dumper per load : 5.00 cum

Loading cycle time:
Turning / moving and spotting : 1 minute
Loading muck by convey mucker and work force : 20 minutes
Cycle time of loading dumper per load of 4.50 cum : 21 minutes
Haulage cycle time:
Running time from loading point to dump yard @ av 10 km / hr : 3.0 minutes
Turning and unloading : 2.0 minutes
Return trip to reversing point @ av 15 km / hr : 2.0 minutes
Cycle time for haulage per load of 4.5 cum : 7.0 minutes
Since the waiting time will be more than the running time if 2 dumpers are deployed deploy
1 dumper for conveying muck.
Round trip cycle time of dumper say : 30 minutesQuantity of muck disposal per hour / dumper : 9.00 cum
