Abstract
IUP. Tanah Urug Ngadimin is an Exploration IUP. which processes
landless commodities for mining activities located in the area of Hargomulyo
Village, Kokap District, Kulon Progo Regency, Special Region of Yogyakarta. To
find the potential of soil corp resource and resource estimation needs to be done.
Resource estimates play an important role in determine the quantity, quality and
easy of commercial exploration of a sediment. Resource of estimates are several
methods that can be used to estimate the amount of soil resources such as polygon
methods, contour methods, cross section methods or the other geometry methods.
The scientific of method used is the cross section method. This cross section
method was chosen because this method is simple, easy to apply, easy to
understand, easily adapted to all mineral deposits, and the estimated completion
time is fast, and for application to sediment deposits which generally have high
homogeneity.
The problem that is the need for estimation of soil crop resources to
determine the magnitude of soil crop quantity in the research area, which can be
estimated by the cross section methods with rule of gradual changes and rule of
nearest point. Limitation of the problems in this study are the method used to
calculate soil crop resources using the cross section method with rule of gradual
changes and rule of nearest point and modeling the soil crop resource used to
AutoCad 2007 software.
The results of parameters obtained such as geological data, map of scale,
outcrop, test pit, and limited level of confidence. The classification of resources is
included the classification of inferred mineral resources.
The result of calculation using cross section method with guidance rule of
gradual changes obtained by volume equal to 763.497,69 m3 while with rule of
nearest point is obtained equal to 763.499,05 m3. The results of the cross section
rule of nearest point method resulted in a larger volume of resources than the rule
of gradual changes.
This difference can occur because the calculation of soil crop resources
with the gradual changes the distance between the incisions in the distance of two
incisions adjacent to each other and it takes two sections to get one volume. While
on the rule of nearest point the incision position is in the middle and has the same
influence distance (½ L) to the left and right of the incision line, and it takes one
cross section to find one volume. In other words the influence of analytical
interpretation on both methods is not comparable. The result of soil crop estimate
pessimistic is 763.497,69 m3.
