Introduction<\/strong><\/p>\n

In quarrying, the quality of your explosives defines the quality of your operation. From the precision of fragmentation to the safety of every blast cycle, the right commercial explosives technology transforms a standard quarry into a high-performance production site.<\/p>\n

At ELTEK SA, we are proud that quarries throughout Greece, Eastern Europe, and the Scandinavian countries have trusted and used our commercial explosives for years \u2014 and continue to rely on them for their most demanding operations. This deep, long-standing trust from the quarrying industry across an entire continent speaks volumes about the performance, reliability, and technical excellence of our products.<\/p>\n

As the fastest-growing explosives production and trading company in Southeastern Europe, ELTEK brings together Swiss engineering heritage \u2014 through our strategic partnership with Soci\u00e9t\u00e9 Suisse des Explosifs (SSE) \u2014 and cutting-edge manufacturing to deliver a complete range of blasting solutions purpose-built for quarry environments.<\/p>\n

Discover how ELTEK SA\u2019s advanced emulsion explosives \u2014 including Explo ANFO, Explo Gel 100, Explo Gel 200, HYDRA 6000 & 750S \u2014 deliver superior fragmentation, safety, and cost efficiency for quarry operations across Europe.<\/p><\/div>\n

Why Quarry Blasting Demands Precision Explosives Technology<\/strong><\/p>\n

Modern quarrying is far more than simply breaking rock. It requires a sophisticated balance of energy distribution, fragmentation control, environmental compliance, and cost optimization. The explosives used in quarry blasting must deliver consistent detonation velocities, predictable gas volumes for effective displacement, excellent water resistance for variable borehole conditions, low toxic fume emissions for regulatory compliance, and reliable performance across different rock formations and geological conditions.<\/p>\n

ELTEK\u2019s product portfolio has been engineered to meet every one of these demands, providing quarry operators with a comprehensive toolkit that covers everything from standard bench blasting to the most challenging wet-hole applications.<\/p>\n

ELTEK\u2019s Commercial Explosives for Quarry Operations<\/strong><\/p>\n

Explo ANFO \u2014 The Reliable Workhorse for Dry-Hole Quarrying<\/strong><\/a><\/p>\n

Explo ANFO is a general-purpose explosive produced by mixing porous ammonium nitrate with diesel oil, achieving uniform distribution through precision spray nozzles (injectors). It remains the most widely used product in quarry blasting worldwide, and ELTEK\u2019s formulation delivers exceptional free-flow characteristics for optimal loading in vertical boreholes.<\/p>\n\n\n\n\n\n\n\n\n
Density<\/strong><\/td>\n0.80 g\/cm\u00b3<\/td>\n<\/tr>\n
Detonation Velocity<\/strong><\/td>\n>2,500 m\/s<\/td>\n<\/tr>\n
Heat of Explosion<\/strong><\/td>\n3,649 kJ\/kg<\/td>\n<\/tr>\n

Relative Weight Strength (RWS)<\/strong><\/td>\n100%<\/td>\n<\/tr>\n
Borehole Diameter<\/strong><\/td>\n>65 mm (surface), >40 mm (underground)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Explo ANFO provides optimal charge density because the explosive column fills the entire borehole diameter, resulting in maximum rock fragmentation at the lowest operational cost per cubic meter. It is initiated with a booster (Explo Gel 100) placed at the base of the hole, using non-electric or electric detonators and detonating cord.<\/p>\n

Explo Gel 100 \u2014 Cap-Sensitive Performance for Surface Applications<\/strong><\/a><\/p>\n

Explo Gel 100 is a cap-sensitive explosive emulsion designed specifically for quarries, surface applications, road construction, and other projects requiring reliable blasting. It also serves as a powerful booster for less sensitive products such as Explo ANFO and Explo Gel 750S, making it an incredibly versatile component in any quarry\u2019s blasting program.<\/p>\n\n\n\n\n\n\n\n\n

Relative Bulk Strength (RBS)<\/strong><\/td>\n130%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Key advantages include excellent water resistance, very low release of toxic fumes, high gas volume production, excellent safety against mechanical impact and friction, and easy loading. Available in cartridge sizes from 28\u00d7410 mm to 90\u00d7540 mm.<\/p>\n

Explo Gel 200 \u2014 High-Performance for Demanding Quarry Environments<\/strong><\/a><\/p>\n

Explo Gel 200 is a high-performance, safe-to-use, cap-sensitive explosive emulsion that combines great detonation speed and high energy during firing. It contains aluminium powder to enhance its energy output, making it suitable for both underground and surface quarry operations across all rock types.<\/p>\n\n\n\n\n\n\n\n\n
Density<\/strong><\/td>\n1.15 \u00b10.05 g\/cm\u00b3<\/td>\n<\/tr>\n

Explo Gel HYDRA 6000 \u2014 The Flagship for Hard Rock Quarries<\/strong><\/a><\/p>\n

When quarries face extremely resistant rock formations, Explo Gel HYDRA 6000 is the definitive answer. As the flagship emulsion of the Explo Gel series, it combines the highest detonation velocity and unrivalled energy output in the ELTEK product range. It is the top choice to replace the use of gelatine dynamite, delivering excellent results.<\/p>\n\n\n\n\n\n\n\n\n\n
Density<\/strong><\/td>\n1.22 \u00b10.05 g\/cm\u00b3<\/td>\n<\/tr>\n

With its aluminium-enhanced formulation and exceptional energy delivery, HYDRA 6000 is purpose-engineered for quarries dealing with basalt, granite, gneiss, and other extremely hard formations where conventional products fall short.<\/p>\n

Explo Gel 750S \u2014 The Solution for Large-Diameter, Water-Bearing Boreholes<\/strong><\/a><\/p>\n

Many quarry operations face the challenge of water ingress in boreholes. Explo Gel 750S is a booster-sensitive explosive emulsion with high density (1.25 g\/cm\u00b3), specifically designed to sink into boreholes containing water and even mud suspensions. It releases a large amount of energy and produces large quantities of satisfactorily crushed aggregates in soft and fragmented rocks, achieving low mining costs.<\/p>\n\n\n\n\n\n\n\n\n\n
Density<\/strong><\/td>\n1.25 \u00b10.05 g\/cm\u00b3<\/td>\n<\/tr>\n
Detonation Velocity<\/strong><\/td>\n5,000 \u00b1 200 m\/s (without confinement)<\/td>\n<\/tr>\n
Heat of Explosion<\/strong><\/td>\n2,720 kJ\/kg<\/td>\n<\/tr>\n
