General quarrying procedure

For the one year we are going

to operate the plant 312 days

and the quarry 300 days.

operate the plant 26 daysand the quarry 25 days per

month.

Purchase the largest practical container

(containers usually end up as waste), but

do not Purchase more than is needed.

Purchase the least toxic or hazardous

product available. Check the material

safety data

Sheets for products you purchase. If the

product is toxic or hazardous, ask your

supplier for alternatives.

See if the supplier can take back excess

Make sure all items are clearly labeled.Store products in original containers.

Store wastes separately and be sure they

are properly labeled to make it easier to

reuse or recycle them.

Store items that could leak in a place

where leaks will be contained and easily

spotted.

Make a list of your wastes. Then try to

The access roads for the aggregate stock

pilesand quarryhave been well defined to

minimize the freight traffic in the

crusher plant site and parking points.

Crusher plant is 150m away from the

administration segment.

Production and the Life time of

the quarry

Production is depending on the

demand of the outside (buyers)

and the production rate of the

machines (crushers, screens,

loader).

Volume of the rock= 100*100*85

= 850000

Life time of the quarry =

850000/6172.84

= 137.7 months
