Abstract

Road is one of the important aspects to support transportation activities. Appropriate road geometry can contribute greatly to the safety and smoothness of transport activities. In addition to the road geometry, water can also affect the condition of haul road, from which it can indirectly affect the transportation activities. Therefore,it is important to conduct an evaluation of the haul road geometry condition based on the AASHTO theory, and to design drainage on the road side of the mine. Road geometry at PT. Sumber Anugerah Buana has not suitable yet based on AASHTO theory. This is proven by using the actual result showing that the the width of straight road was 4 - 7,5 meter, and the width of bend road was 5.3 - 5,5 meter. However, according to AASHTO theory, the width of straight road should be 4,850 meter and the width of bend road should be 7,733 meters. So, it is necessary to add width on straight road in segment IJ and in all segment of bend road. The slope of the mine haul road at PT. Sumber Anugerah Buana already has a safe slope of the road, except the A-B segment and D-E segment that are still above the safe condition, which is more than 15%. PT. Sumber Anugerah Buana does not have drainage, so it is necessary to make channel on the first DTH dimension, that is 0,463 meter wide, 0,701 meter deep, and 0,928 meter wide of the channel surface. Meanwhile, the dimension for the second DTH should be 0, 260 meter wide of the channel bottom, 0.395 meter deep of the channel, and 0,522 meters wide of the channel surface.

Abstract

Drilling and blasting activities in PT. Semen Bosowa Maros quarry aims to dismantling limestones of the host rock with fragmentation expected size of ≤100 cm, considered the maximum size of rock crusher receive opening. The drilling pattern used is staggered pattern, while blasting pattern used is blasting streak pattern, with ignition of one line and straight lines of the one between next line. Based on observations in the field, the boulder that came from the blasting activities are relatively high at 20.63 %. To reduce the resulting chunks of the rock blasting activity, it’s important to change the geometry of blasting base formulation expressed by R. L. Ash, thus changes the distance to 3.1 m; spacing to 3.7 m; stemming height to 3.14 m; bench height to 5.80 m and depth of blasting hole to 6.10 m. With the new blasting geometry, lump sized rocks >100 cm generated from operating activities actual blasting theoretical calculations amounting only 14.82 %.

Abstract

In a mining company, of course, has a risk management system that aims to be able to identify any potential hazards that can occur around the mining and processing area and to make controls before a work accident occurs. One of the characteristics of the mining industry is that it is capital intensive, technology intensive and high risk, so it is necessary to identify and analyze risks for every job in the field, the method used in analyzing potential hazards and risk analysis is the Job Safety Analysis method which aims to identify and analyze each work steps and look for solutions or control methods if there is a potential hazard that can result in a work accident, one of the steps or efforts to protect workers in the field is to use personal protective equipment so that workers can be protected if at any time a work accident occurs in the field.
