Site-mixed bulk emulsion explosives have been used in the European quarrying industry since the early 1990s and have become well established as the explosive of choice in many operations and are.John Frank
Good blast design and execution are essential to successful mining operations. Improper or poor practices in blasting can have a severely negative impact on the economics of a mine. The use of excessive explosives at a mine site can result in damages to the rock structures and cause unwanted caving and large increases.

Dykon Blasting, Quarry Division offers drilling and/or blasting programs for the aggregate industry. Each Quarry has unique needs which are specific to its operation. We provide each quarry with a specialized analysis identifying their specific needs and then develop a tailor made blasting program to fit those requirements.
Blasting is a primary means of extracting minerals and ores at surface mining operations. . Flyrock from surface blasting operations has caused . resistance could generate flyrock, depending on the blast site conditions. A combination of 'borehole tracking' and 'laser profiling' can assist in improving the design of a blast.
Our people utilize the latest technologies, including EDT-Electronic Detonator Technology, laser profiling, bore tracking, videotaping, and seismic monitoring. Our fully-staffed, in-house Engineering Department defines scopes, and prepares site volumes surveys for the development of comprehensive quarry plans.
