Coal Stockpile Management In CV. Putra Parahyangan Mandiri Satui, Tanah Bumbu, South Borneo

Abstract

Utilization of natural resources, especially coal mining at this time is developing rapidly
progress along with big market demands. So that, there are many mining companies
located and open new sites of coal mining gradually, in order to fulfill the market needs,
both International and domestic markets. For increasing coal production, optimization
reducing production costs is needed to obtain the optimal profits.
CV Putra Pratama has constraints in terms of the process of stacking and removal of
coal that affected the quality of the coal. In heaps of raw coal, the patterns that used are
cone play by using 3 dump trucks and 3 wheel loaders. Then coal is transported to
Hooper's crushed and become a pile of coal, and then the coal is loaded into the ship
by using 4 dump trucks and 2 wheels loader. Coal production is 101.243,72 ton/month.
Transformation of coal quality that occured from the pit mining to stockpile ash is
increasing to 4.3%. The increasing percentage of ash because of contamination at the
mind, which is commonly borne contamination when exposed coal among others
overburden which came from clay, soil and other tailing materials. Heavy machineries
and plant equipment that used in stockpile area are routinely maintenance in order to
avoid the ash rises. Utilization of spray water can be done to anticipate the ash. Fog
spray ( as the one type of pray water ) is recommended to tide the dust optimally.
