Abstract

Abstract. Flyrocks is a situation where a miss occurs due to a problem when blasting occurs. Some things that might cause a flyrock are no free face, inappropriate stemming, shallow holes and too many rows. It is expected that with the appropriate geometry can minimize the impact of flyrock that occurs during blasting because it can endanger the tools, buildings and humans that are around the blasting. The research location is in CV Tekad Jaya. The study was conducted by measuring the actual maximum throw distance of the flyrock in the field. Observations were made 35 times. Estimated flyrock throw distances use two methods namely Richard and Moore's theory (2005) to see the impact of stemming and burden on flyrock and Abraham Ghasemi (2012) to see the impact of PF on flyrock. From the estimation results a new geometry was designed using the RL Ash and CJ Konya methods to get a new geometry that has a minimum flyrock. Then obtained nominal burden, stemming and PF of 1.9; 1.43; 0.494 for RL Ash and 2.2; 1.7; 0.397 for CJ Konya. With the geometry obtained flyrock throw distance between 12m to 40m which can be said to be safe for the company.Keywords: Blasting, Flyrock, Geometry, RL Ash, CJ Konya

Abstract. Iron sand is generally a beach of iron sand which is widely spread, including along the west coast of Sumatra, the southern coast of Java and Bali, the beaches of Sulawesi, East Nusa Tenggara, Maluku and the north coast of Papua. Iron sand contains magnetic minerals which are materials for building tools in modern life. The great potential in South Nagari Tiku must also be followed by a market that is able to absorb the product. To find out the market potential, it is necessary to analyze the quality of iron sand in both regions. So it can be determined whether the potential in the area can have economic value or not. Nagari Tiku Selatan is located in Tanjung Mutiara District, Agam Regency, West Sumatra Province. Area of Nagari Tiku Selatan: 31.42 KM2 or 15.27% of the total area of Tanjung Mutiara District. Nagari Tiku Selatan is the capital of the sub-district, located 20 KM from the district capital and 92 KM from the provincial capital. This study aims to determine the amount of resources (quantity) and quality of iron sand in the area, using a combination of direct exploration and indirect exploration. Based on the results of the study it was found that the resource of iron sand from the area obtained from handbor lithology was 199,680 tons while from geolistrik measurements the volume was 7,987,200 tons. The total area containing iron sand in the survey area is 249,600 m2 and the total survey area is 2.3 km2. With the specific gravity obtained from physical tests of 3.2. While the quality of iron sand in the area contains between 10-20% Fe2O3, while TiO2 content between 0.6-1.7% is obtained from the analysis of samples tested in the laboratory using the XRF method.Keywords: Iron Sand, Handbor, Geolistrik, Exploration, Resources

Abstract

Abstract. Coal transportation is important in achieving coal production targets. The condition of road geometry is one of the factors that influence transportation activities. The purpose of this research is to conduct a technical study of the geometry of the coal haul road from the Sumatra Jambi-Palembang crossroads to the special port owned by PT Baturona Adimulya to achieve the coal production target. The study was conducted by direct observation to the field to obtain primary data and secondary data needed. The results of the data analysis show that the geometry of the mining road still needs to be improved in certain segments. The actual condition of the width of the B-C (bend) and E-F (straight) segments of 10.6 m and 8.5 meters wide is not yet ideal, so it is necessary to increase the width of the road respectively in the width of 0.7 meters and 0.5 meters. The actual slope of the road in all segments is ideal. The actual superelevation of the F-G segment valued at 0.29 m is not ideal yet, so the elevation outside the bend needs to be added at 0.15 meters. The actual cross slope, segments A-B and E-F, respectively 10 cm and 15 cm, are not yet ideal, so it is necessary to add height to the middle of each segment as high as 8 cm and 3 cm. Production of conveyance before repairing was 56.2948.98 tons and after repairing the road geometry was 60.144.92 tons.Keywords: Transportation Geometry, Improvement Plan, Production Target, Cycle Time, Technical Study

Abstract

Abstract. Soil and rock material has less strength to tension, compared to pressure and shear. Tensile strength has an important role in the stability of mining activities such as drilling, blasting and making slopes and mine tunnels. Determination of the tensile strength value is currently done by testing the indirect tensile strength (Brazillian Test). In the field commonly, to prediction tension strength value used rule of thumb which is the result of analysis from previous tests, but for this case, the prediction results using rule of thumb are inaccurate. The sample used in this research is sedimentary rock taken from several coal mining locations in the Jambi province. This sample is then tested using a compressive machine to get the uniaxial compressive strength and tensile strength values. Descriptive statistical methods and linear regression methods are used in this study to obtain an accurate prediction of tensile strength based on compressive strength data. According to the descriptive statistical method the tensile strength value is 0.41 times the compressive strength value, while if it is linear regression, the result of the tensile strength value is equal to 0.2079 σc + 0.1917. Both of these methods are able to predict the value of the tensile strength better than the existing rule of thumb, but more advanced research with more samples is needed to get the better equation.Keywords: Sedimentary Rock, Brazilian Test, Tensile Strength, Compressive Strength, Prediction
