Abstract :
ABSTRACT
Dusun Kwagon, Desa Sidorejo, Kecamatan Godean, Kabupaten Sleman,
Privinsi Daerah Iistimewa Yogyakarta is a region with most of its people working
as roof tiles and bricks maker. The existence of traditional roof tiles and bricks
which is handmade are as good as those from the factory with modern technology.
According to Yogyakarta Regional Geology Map, the region has tons of
claystones which are the main material for making roof tiles, bricks and other
industry that uses clay stones.
Along with the need and high demand from the market regarding the
material for making roof tiles and bricks, therefore leads to mining operation in
the area. This will contribute economically with more income and improve
welfare for the miner, the company, as well the craftsmen. This research will try
to give recommendation regarding the geometry design of the mining slope that
cover: height, width, and angle of slope in a safe and stable condition. Through
probability method approach by using Monte Carlo Method, input parameters are
required such as average value, deviation standard, maximum and minimum
relatives along with software slide 5.0 for data analysis. It will obtained
Probability of Failure (PoF) value or trust value on a planned slope geometry
design. PoF will represents with percentage value (%).
According to the research?s result, there are three recommendations for
altitude 105 m and the first single slope the height is 5 m, 310 for the slope?s tilt,
with 3 m for width, 240 overall slope, and possibility of the slope for avalanche is
17,2%. The second of single slope the height is 5 m, 350 for the slope?s tilt, with 4
m for width, 250 overall slope, and possibility of the slope for avalanche is 18,6%.
The last single slope the height is 5 m, 280 for the slope?s tilt, with 5 m for width,
240 overall slope, and possibility of the slope for avalanche is 16,8%. The result is
based on a threshold value from % PK on SRK Table (2010) and can be seen on
Table 3.2.
