Abstract

Perkembangan teknologi detonator elektronik semakin pesat seiring dengan semakin banyaknya fitur-fitur terbaru yang lebih memudahkan operator dalam proses penggunaannya. Salah satu teknologi elektronik terbaru yang diperkenalkan adalah Hanwha Electronic Blasting System generasi kedua (HEBS II) sebagai detonator elektronik yang menggunakan aplikasi berbasis android, dimana proses penanganan dan pengoperasiannya lebih mudah. HEBS II memiliki tiga sistem operasi diantaranya tagging, logging, dan scanning, yang dapat digunakan sesuai kebutuhan. Sistem operasi mencakup 4 jenis metode diantaranya adalah mode dasar, open pit, terowongan, dan mode perangkat lunak. Chip HEBS II memiliki tingkat keakuratan atau presisi hingga 0.01% untuk peledakan antar lubang dengan waktu tunda maksimum 50.000 ms. Rangkaian peledakan dapat diledakkan pada jarak jauh dan dapat diperpanjang sampai jarak maksimum 5 km dari area peledakan, dengan menggunakan kombinasi repeater yang tentunya praktis dan lebih aman. Semua software peledakan dapat diterapkan ke sistem HEBS II dan dioperasikan dalam mode perangkat lunak. Dengan beberapa  keunggulan tersebut, dapat memungkinkan untuk mencapai peledakan yang optimal, efisien, ekonomis, dan ramah lingkungan. HEBS II lebih efektif untuk menghasilkan proporsi ukuran fragmentasi yang lebih kecil dibandingkan dengan sistem piroteknik yang lebih tinggi, dengan tingkat keseragaman per layer batuan mencapai 82% bila dibandingkan dengan detonator non- elektrik yang hanya mencapai 62%. Tingkat reduksi ukuran fragmentasi mencapai 31% dari layer pertama ke layer kedua. HEBS II mampu mereduksi tingkat getaran sebesar 45% dari getaran yang dihasilkan oleh detonator non-elektrik.

Abstract

Sebuku Tanjung Coal, a mining company, has a blasting location close tobuilding structures. This building is included in the Class 2 building on SNI 7571:2010 with a maximum peak vector sum (PVS) value of 3 mm/s or peak particle velocity (PPV) value of 3 - 7 mm/s at the frequency of 0-100 Hz. Several critical areas are located between 200 and 700 meters from the blasting location. The used initiation system is Hanwha Electronic Blasting System 2nd Generation (HEBS II), which uses HiMex 70 (emulsion) as an explosive type. In this paper, the tie-up design of blasting uses segment and non-segment methods to compare the results of blasting using the two methods. Based on 16 compared data points, the vibration results obtained using segment and non-segment had a value range of 2,767-15,102 mm/s. The average result of the digging time using the segment method is 10.9 seconds, while the non-segment method takes 10.3 seconds. The average size of fragmentation (D80) with the segment method is 49.1 cm, while the non-segment method is 45.4 cm.

Abstract

Fly rock is a rock fragmentation that is thrown as a result of blasting. Such fragmentation that is thrown beyond the specified safe distance can cause a damage to the infrastructure, mechanical equipment and humans. This study aims to determine the safe radius of the fly rock that resulting from blasting residential area which that has a distance 200-300 m and has potentially distressing to cause damage. Calculating of the flying rock throwing distance is carried out theoretically and actually with orientation to the distance between spaces, the distance between burdens, minimum stemming height, minimum hole depth, powder factor, average charge blast hole and distance initial burdens. For theoretical calculations, the save distance is calculated by empirical methods and dimensional analysis. Results of the study shows that the maximum distance of the actual fly rock throw is 05.31 m and based on the predictions using the Cratering Method, the maximum distance of fly rocks is 172 m with a safety factor of 2 and the maximum distance of fly rocks is 199.04 m with a safety factor of 2. Based on the actual and predicted data above, it is not safe for blasting locations that is less than 200 m from residential areas, that refers to the safe radius threshold based on the regulation of the Minister of Energy and Mineral Resources No. 1827 K/30/MEM/2018.

Abstract

The method of rock breakage is commonly blasting. A few mining companies in Indonesia with facilities near community residences use alternative methods to breaking rock; one of them is using a surface miner. Aspects considered when choosing the method include economic aspects, especially operating costs. In this study case, the size of material that can continue on the next process is ≤ 400 mm; material from surface miner production is at the target; on blasting results, the fragmentation above the target is reduced using a hydraulic breaker; the initiating systems use an electronic detonator (HEBS II) and a non-electric detonator. This difference will affect the cost of the drill and blast. Based on calculated project data, surface miner operating costs are more costly, with an operating cost per ton of USD 1.16 compared with drill and blast methods including hydraulic breaker costs on the initiation system using an electronic detonator (HEBS II) of USD 0.88 per ton and non-electric operating costs of USD 0.83 per ton.

Abstract

Salah satu dampak yang ditimbulkan akibat peledakan overburden batubara adalah getaran. Getaran ini dihasilkan dari sisa energi peledakan yang merambat pada struktur batuan, yang dapat menyebabkan kerusakan pada bangunan. Di Indonesia, pemerintah mengatur pembatasan getaran pada SNI 7571:2010. Dalam hal ini Sebuku Tanjung Coal yang merupakan perusahaan tambang yang melakukan kegiatan peledakan untuk menghilangkan lapisan tanah penutup batubara dan lokasi peledakan dekat dengan struktur bangunan (rumah umum), khususnya di Pit T3. Struktur gedung ini termasuk dalam gedung Kelas 2 pada SNI 7571:2010 dengan nilai Peak Vector Sum (PVS) maksimal 3 mm/s atau nilai Peak Particle Velocity (PPV) 3-7 mm/s pada frekuensi 0- 100 Hz. Jarak beberapa critical area dari lokasi peledakan sekitar 200-700 m. Sistem inisiasi yang digunakan adalah Hanwha Electronic Blasting System 2nd Generation (HEBS II) kombinasi HiMex 70 (Emulsion) sebagai bahan peledak. Pada makalah ini, desain tie-up peledakan menggunakan metode segment dan non- segment untuk membandingkan hasil peledakan dari kedua metode tersebut. Berdasarkan 16 perbandingan data yang diperoleh, diperoleh hasil vibrasi menggunakan segmen dan non segmen dengan rentang nilai 2,767-15,102 mm/s. Hasil rata-rata waktu penggalian dengan metode segmen adalah 10,9 detik, sedangkan metode non-segmen adalah 10,3 detik. Ukuran rata-rata fragmentasi (D80) dengan metode segmen adalah 49,1 cm, sedangkan metode non-segmen adalah 45,4 cm.
