Abstract
ABSTRACT
PT Sugih Alamanugroho is a limestone mining company which is located
in the village of Bedoyo, District Ponjong, Gunung Kidul, Yogyakarta.
Assessment of the resources obtained through the calculation and analysis of the
data that is detailed exploration drilling and mapping of data.
Mineral resource assessment limestones at. Sugih Alamanugroho aims to
estimate the volume and tonnage of limestone resources in Mount Pokerso. This
assessment is done by using two methods, namely Cross Section and Contour
method.
In the cross section method performed by making an incision (crosssection).
An
incision
is
made
as
many
as
14
incisions
were
divided
into
13
blocks,
from
the incision A-A ', incision B-B', incision C-C 'until the incision N-N' with
the distance between the incision 25 meters. While the method is done digitized
contour at each contour is at 430 meters above sea level with the highest interval
contour interval of 5 meters, consisting of nine contour is divided into 8 blocks.
Both of these methods are based on the topography of limestone sediment that
consists of the topography of peaks, slopes and valleys, using the guidelines of
gradual change (rule of gradual change).
Limit estimate of the elevation of 430 meters above sea level - 390 meters
above sea level, with an area of 5 ha area of research. The material covered is
limited to the assessment of the resource alone.
Results of the resource estimation using the Cross Section with the
guidelines of the gradual change in the distance between the incision 25 meters
obtained measured mineral resources amounting to 1,225,577.28 tons. As for the
method Contour with the guidelines of the gradual change in the contour interval
of 5 meters measured mineral resources sebesr obtained 1,246,145.17 tons.
Mining objectives targeted by PT. Sugih Alamanugroho amounted to 544
320 tonnes / year, so it can be calculated the mine life. Crosss section for the
method and to methods of contour is 2.5 years. Limestone in the study area used
for the base material of which is industrial paint industry.
