DATA:Capacity of shovel bucket : 0.85 cum

Capacity of shovel bucket under heaped condition : 1.00 cum

Capacity of dumper : 5.00 cum

initial lead considered for analysis : 1.00 km

Speed for loaded tipper under haul road condition : 15 km / hr

Speed for empty tipper under haul road condition : 20 km / hr

Turning and unloading time : 2.00 min

Shovel digging and loading cycle per bucket : 50 sec

Number of buckets per load ( 5.00 / 1.00 ) say : 5 buckets

Ideal cycle time for loading 5 buckets ( 5 x 50 / 60 ) : 4.17 min

The ideal cycle time for shovel requires spotting of a dumper within 4.17 minutes near the

shovel. However, in practice the space available at quarry may not permit positioning of tipper

for loading on either side of shovel. Generally one tipper has to move after loading to position

the next tipper for loading. Assuming one extra cycle for shovel, the corrected cycle time

for the shovel will be : ( 4.17 + 50 / 60 ) : 5.00 min

Round trip cycle time for tipper:

Ideal cycle time of shovel for digging & loading : 5.00 min

Time for 1km haulage under load ( 60 / 15 ) : 4.00 min

Output for 3 tippers per day ( 3 x 16.67 x 8 ) say : 400 cum

The bulkage of graded rockfill material for conveyance is assumed at about 40 to 45 percent.

Considering av. 42.5 % bulkage, insitu qty will be ( 400 / 1.425 ) say : 281 cum

Consider 2 % wastage of rock in handling.

Insitu quantity of rock available for rock f il l layer ( 281 x 0.98 ) say : 276 cum

Assume 30 % voids in graded dozer levelled and hand packed rockfill.

Quantity of rockfill in layer ( 276 / 0.70 ) say : 394 cum

Quantity of overburden soil / soft rock for 32 sqm ( 32 x 1 ) : 32 cum

Consider removal of overburden by manual labour.

Consider output of 1 heavy and 1 light mazdoor @ 4 cum / day.

2. Drilling and Blasting :

As the density of rockfill is dependant on gradation the drilling and blasting operations at quarryshall be planned properly to produce graded material.

For 300 mm down size rockfill consider 32 mm dia jack hammer drilling.

For good fragmentation consider burden at 25 times dia of hole say : 0.80 m

Consider spacing at 1.25 times burden : 1.00 m

Grid spacing of holes in m : 0.80 x 1.00 m

Depth of hole ( generally not less than twice the burden ) : 2.40 m

Effective depth of hole ( 2.40 - 0.15 ) : 2.25 m

Area of excavation for 281 cum ( 281 / 2.25 ) : 125.00 sqm

Nos. of holes for 125 sqm area 125 / ( 0.80 x 1.00 ) : 156 Nos.

Depth of drill ing for 156 holes ( 156 x 2.40 ) : 375 m

Add for secondary drilling @ 5 % holes of 0.6 m depth say : 5 m

Tota depth of drilling including holes for secondary blast ( 375 + 5 ) : 380 m

No. of secondary blast holes : 8 Nos

Rated rate of drilling in hard rock by jack hammer : 8.00 m / hour
