32 AUGUST 2023 WorldWide Drilling Resource® www.starironworks.com 257 Caroline Street Punxsutawney, PA 15767 800-927-0560 • 814-427-2555 Fax: 814-427-5164 SERVING THE WATER WELL INDUSTRY Serving the Drilling Industry New Bulk Emulsion System for Underground Operations Adapted from Information by Orica Orica recently unveiled a new range of 4D™ bulk explosives for the underground market. Designed for production and development applications, the Subtek™ 4D range enables underground operators to gain exceptional control of energy through a single explosive solution. Following the launch of the 4D bulk systems for surface operations in 2021, Orica has developed a new bulk emulsion explosives delivery system for underground operators that allows precise control of in-hole explosive energy. Subtek 4D offers the widest available energy range, with the ability to accurately match energy with varying rock properties and mine design requirements. In combination with Orica’s proprietary emulsion chemistry, the suite of smart explosives delivery technologies integrated with the new 4D MaxiLoader™ allows instant application of selected energy into the blasthole to match any complexity of blast design, as well as adjust energy between blastholes or within an individual blasthole. Orica Chief Technology Officer Angus Melbourne said, "Our new 4D underground bulk emulsion system is all about delivering a precise, predictable product energy in the blasthole that ultimately gives our customers the capability and confidence to execute designs that are not possible today, where energy is matched to geological and mine design needs. The result is very targeted blasting that facilitates optimal recovery of valuable ore bodies while ensuring the most efficient use of rock breaking energy from mine to mill. 4D is a breakthrough solution that will unlock sustained value for our customers." Consistent and repeatable execution of the charging process is also a key capability of the system, where the loading process is automated through Orica’s LOADPlus™ smart control system. This ensures optimal application of the product within the blasthole, while a wide range of usable bulk strength options matches energy distribution to ore body conditions and mine design requirements. The outcome is maximized ore body recovery, reduced dilution and rework through overblasting, and better fragmentation while optimizing explosives consumption. Designed to offer superior blasthole retention and zero waste energy, the 4D innovation maximizes the efficient use of explosive energy, minimizes downstream energy consumption, and reduces potential environmental impacts due to residual or wasted product.
