Abstract
CV . Cintapuri Pratama is a company engaged in coal mining . CV mining
sites . Cintapuri Cintapuri Primary in the village , Banjar Baru , South
Kalimantan.
The problem faced by CV . Primary Cintapuri one of which is a problem
because there is no draft mine draining system which will result in many puddles
on the work area occur mainly during the rainy season . It is very disturbing and
working conditions affect production . The main source of mine water in the coal
mining area by CV . Primary Cintapuri is rainwater . Plan 123 mm rainfall / day
with rainfall intensity of 20.38 mm / h and rainfall return period ( PUH ) 5 ( five )
years.
Location mine draining not have an adequate system . Areas which
become providers rain water and run off water on site mining plan is divided into
6 Catchment Area .
a.Catchment Area I, area = 0.5247 km2
b.Catchment Area II , area = 0.1152 km2
c.Catchment Area III , area = 0.0049 km2
d.Catchment Area IV , area = 0.0093 km2
e.Catchment Area V , area = 0.0287 km2
f.Catchment Area VI , area = 0.0453 km2
The volume of water that enters the mine at 2.3987 m3/second . Open
Channel planned is a combination of mine drainage and mine dewatering . Mine
Drainage channel made in the KP boundary in order to prevent the ingress of
water from outside the mine site , namely :
a. Open Channel 1 : a = 0.7 m , b = 0.7 m, B = 1.3 m, α = 60o
With diameter of culvert is 1,2 m
Runoff water that flowed through the channel and then get into the sinks .
Sinks are made with dimensions of length 118 m , width 60 m , and a depth of
sinks is 5 m . After the water is pumped into settling ponds . Pumps are needed as
much as 1 unit vertical centrifugal pump type pump with a maximum discharge of
540 m3/second pump . In the flow of run off water itself contained dissolved
material was 121 mg / l , and the percent solid on settling ponds at 1.35 % . With
such a large percent of the solid , long deposition of material required for 3 days .
The dimensions of the settling ponds is 28 m long , 12 m wide , and a depth of
settling ponds is 4 m with a volume of 1152 m3 settling ponds . Ultimately
expected after discharge from the settling ponds , the water that comes out will not
pollute the environment around the mine .
