Abstract

The uniaxial compressive strength test was carried out to determine the value of rock strength. This research was conducted on sandstones in the Pamaluan Formation. The tests carried out in this study were physical properties tests, compressive strength tests and grain size tests on sandstones with a total of 30 samples on the physical properties test, 10 samples on the mechanical test and 500 gram grain size test at each point, the purpose of which is to determine the effect of porosity on the compressive strength of rock. In testing the physical properties carried out, the lowest and highest porosity values ​​were 17.27 and 22.91%. The results of the compressive strength test with the lowest and highest values ​​were 3.05 and 7.63 MPa. The grain size test results at points 1 and 2 are the same, namely fine sandstones with a percentage of 45 and 44%. From the results of research that has been done the value of porosity and grain size is very influential on the compressive strength test.

Abstract

PT. PAMA is a company engaged in mining and is a contractor of PT. Indominco Mandiri which has been running since 1996. The work contract given is blasting, from blasting activities many impacts arise, one of which is ground vibration, therefore it is necessary to measure the level of ground vibration in the west block area where there are several critical areas in the form of buildings such as offices , solar (fuel oil) storage, and PT. Indominco Mandiri, where there have been complaints regarding large vibrations and the potential for diesel spills from fuel oil. In the study the peak vector sum (pvs) value produced in December 2022 was 1.57 mm/s with the closest distance of 785 meters and in January 2023 4.21 mm/s with a distance of 500 meters. The maximum use of explosives item for explosive holes in December 2022 and January 2023 is 2,513 kg. This pvs value is still safe, because it is still below 5.0 mm/s and according to SNI 7572: 2010.
