Highlights • Blasting is essential in open-pit mining and quarrying for profitability and cost reduction. • Drilling and blasting aim to efficiently fragment rock for processing plants. • …
In rock blasting for mining production, stress waves play a major role in rock fracturing, along with explosive gases. Better energy distribution improves fragmentation and safety, lowers production costs, increases productivity, and controls ore losses and dilution. Blast outcomes vary significantly depending on the choice of the explosive and the properties …
sandstone and shale bands. The Situation Blasting at the quarry was producing oversize rock that needed to undergo secondary breaking with the use of a breaker, which resulted in increased production costs. Hap Seng asked Orica for assistance to improve fragmentation, reduce operating costs and streamline detonator stock management.

If you own or operate a rock quarry, gravel pit, borrow pit, or similar aggregate production operation, use these resources to understand the environmental rules you must follow. These resources will also help you understand the rules for rock crushers, concrete crushers, and other aggregate processing operations.
To do this, BME integrates blast design, blast recording and blast delivery systems. "Integration of blast data allows for easier interrogation of results, which guides the drilling and blasting process to produce consistent, quality blasts," said BME's Global Manager for Blasting Science D. Scott Scovira.
