Drilling<\/span><\/strong><\/h3><p>Specialized mobile platforms called jumbos dominate the initial stage. These machines boast three powerful manipulators functioning as drilling arms and a central operator console for meticulous control. Jumbos are typically tethered to an electrical grid for power.<\/p><p>A critical component is a high-pressure water supply that feeds pneumatic drifters. This pressurized water enables the drill bits to efficiently rotate and hammer the rock face, creating designated cylindrical cavities (boreholes) ranging from 2.4 to 3.6 meters in length.<\/p><p>The number, depth, and precise orientation of these boreholes are meticulously planned based on the desired fragmentation outcome for efficient rock removal and the need for geotechnical stability to ensure the integrity of the surrounding rock mass.<\/p><p>The configuration of the boreholes, known as the drilling pattern, also plays a crucial role. Common patterns include:<\/p><ul><li>Square Pattern: Offers equal spacing and burden (distance between boreholes and the rock face) with rows aligned directly behind each other.<\/li><li>Rectangular Pattern: Similar to the square pattern, but with a larger spacing between boreholes compared to the burden.<\/li><li>Staggered Pattern: Boreholes in each row are offset, creating a honeycomb-like pattern. This optimizes fragmentation while minimizing burden.<\/li><li>Equilateral Triangle Pattern: Similar to the staggered pattern, but with a specific spacing-to-burden ratio for efficient rock breakage.<\/li><\/ul><p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-large wp-image-14335\" src=\"https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine-1024x657.jpg\" alt=\"Drilling in open-pit mine\" width=\"1024\" height=\"657\" srcset=\"https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine-1024x657.jpg 1024w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine-300x193.jpg 300w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine-768x493.jpg 768w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine-18x12.jpg 18w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine-480x308.jpg 480w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drilling-mine.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p><h3><span style=\"font-size: 21px;\"><strong>2. Explosive Charging<\/strong><\/span><\/h3><p>Once the drilling is complete, it's time to load the boreholes with the right explosives. The type of explosive chosen depends on the rock's characteristics. Common options include:<\/p><ul><li>Dynamite Variations: Traditional dynamite is still used in some cases, but it's often replaced by safer and more controllable options like ammonium nitrate fuel oil (ANFO) mixtures.<\/li><li>Water Gels: These gel-like explosives are popular due to their water resistance, making them suitable for wet environments. They also tend to produce fewer fumes compared to traditional dynamite.<\/li><li>Emulsions: Water-in-oil emulsions offer good blasting performance and are less sensitive to shock and fire compared to other explosives.<\/li><\/ul><p>To minimize the inherent risks associated with explosives, mechanized charging equipment is extensively used. This ensures the safe and controlled placement of the explosive materials within the boreholes.<\/p><p>Detonators are attached to each explosive device and subsequently interconnected to form a predetermined blasting sequence. Civil and structural engineers leverage advanced telemetry systems to monitor potentially hazardous areas during this crucial stage, further strengthening safety measures.<\/p><h3><strong><span style=\"font-size: 21px;\">3. Blasting<\/span><\/strong><\/h3><p>Controlled blasting, a common technique that minimizes overbreak (excess rock breakage) and ground vibrations, ensures clean excavations and protects surrounding structures from damaging tremors.<\/p><ul><li>Pre-Splitting: Creates a clean fracture plane using a single row of precisely placed and detonated holes, minimizing overbreak in the main blast.<\/li><li>Smooth Blasting: Used in underground mines, this method involves detonating lightly charged holes along the final excavation line after the main blast, creating a smooth and stable wall with minimal overbreak.<\/li><li>Cushion Blasting: Similar to smooth blasting, the holes are <a href=\"https:\/\/www.jouav.com\/blog\/backfilling.html\">backfilled<\/a> with crushed rock to absorb the shockwave and further minimize damage to the final wall.<\/li><\/ul><p>Detonation order is crucial. Blasts are carefully sequenced, typically starting from the center and moving outwards. This ensures optimal rock fragmentation while minimizing vibrations. Precise timing between detonations further refines control, focusing the energy release.<\/p><p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-large wp-image-14327\" src=\"https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction-1024x683.jpg\" alt=\"Drilling and blasting in Construction\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction-1024x683.jpg 1024w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction-300x200.jpg 300w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction-768x512.jpg 768w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction-18x12.jpg 18w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction-480x320.jpg 480w, https:\/\/www.jouav.com\/wp-content\/uploads\/2024\/03\/drill-and-blast-construction.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p><h3><strong><span style=\"font-size: 21px;\">4. Ventilation<\/span><\/strong><\/h3><p>Explosions generate significant dust clouds mixed with combustion gases. Ventilation becomes essential to ensure worker safety and a healthy working environment.<\/p><p>Long steel or plastic pipes are used as air ducts. These are often attached to the tunnel's roof and strategically positioned to blow fresh air onto the working face, effectively removing dust and fumes.<\/p><h3><strong><span style=\"font-size: 21px;\">Mucking and Scaling<\/span><\/strong><\/h3><p>After blasting, the fragmented rock, referred to as muck, needs to be removed. This process involves loading the broken rock into hauling vehicles like dump trucks and transporting it out of the excavation area.<\/p><p>Following the initial clearance, a process called scaling is crucial. This involves removing any loose pieces of rock from the crown (ceiling) and walls to prevent potential rockfalls and ensure worker safety.<\/p><h3><strong><span style=\"font-size: 21px;\">Ground Support Installation<\/span><\/strong><\/h3><p>As the tunnel excavation progresses, the newly exposed ceiling and side walls require support to prevent rock falls and ensure tunnel stability.<\/p><p>Several methods are employed for ground support, depending on the specific site conditions. Common options include Rock bolts or dowels: These are long, slender steel bars drilled into the rock and secured with a mechanical wedge or adhesive to reinforce the rock mass.<\/p><ul><li>Shotcrete: A layer of sprayed concrete is applied directly to the rock surface to provide immediate support and strengthen the surrounding rock mass.<\/li><li>Ribs or mining arches and lagging: These are prefabricated steel frames used to create a temporary support structure within the tunnel.<\/li><li>Cable bolts: High-strength cables are grouted into boreholes and anchored behind the rock face to provide additional support and reinforcement.<\/li><li>In-situ concrete: This technique involves casting concrete within the excavated space to create a permanent and robust tunnel lining.<\/li><\/ul>    <\/div>\n<\/section>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e74adc6 elementor-widget elementor-widget-jouav-common-scroll-spy\" data-id=\"e74adc6\" data-element_type=\"widget\" data-widget_type=\"jouav-common-scroll-spy.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<section class=\"common-scroll-spy anchor-point\" data-scroll-spy-title=\"Drilling and Blasting vs. Tunnel Boring Machines (TBM)\">\n         <div class=\"container text-center d-flex justify-content-center align-items-center text-muted fs-7\">\n             <svg class=\"svg-icon me-2 text-primary\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" aria-hidden=\"true\" role=\"img\" viewBox=\"0 0 24 24\"><path  d=\"m17 15l1.55 1.55c-.96 1.69-3.33 3.04-5.55 3.37V11h3V9h-3V7.82C14.16 7.4 15 6.3 15 5c0-1.65-1.35-3-3-3S9 3.35 9 5c0 1.3.84 2.4 2 2.82V9H8v2h3v8.92c-2.22-.33-4.59-1.68-5.55-3.37L7 15l-4-3v3c0 3.88 4.92 7 9 7s9-3.12 9-7v-3l-4 3zM12 4c.55 0 1 .45 1 1s-.45 1-1 1s-1-.45-1-1s.45-1 1-1z\"><\/path><\/svg> Drilling and Blasting vs. Tunnel Boring Machines (TBM)         <\/div>\n<\/section>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-608af23b elementor-widget elementor-widget-common-text-editor\" data-id=\"608af23b\" data-element_type=\"widget\" data-widget_type=\"common-text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<section class=\"common-text-editor\">\n    <div class=\"container\">\n        <h2><strong><span style=\"font-size: 28px;\">Drilling and Blasting vs. Tunnel Boring Machines (TBM)<\/span><\/strong><\/h2><p>Building tunnels is a crucial aspect of modern infrastructure development.
