The experience of blasting with 311 mm diameter holes on 14 m high benches at Kudremukh Iron Ore Project has revealed that expanded drillhole patterns have a tendency to crater. Drilling holes too close was not feasible as the drilling cost and powder factor increased. The larger diameter holes also resulted in higher consumption …
Reduce drill and blast costs. Advanced blasting technology and clever blast design can improve the utilisation of the drilling fleet and reduce capital and operating costs without compromising productivity. Matching explosive energy to geology enables expanded patterns without affecting fragmentation.
Abstract. Pre-splitting is a controlled blasting technique with applications in open pit mines. The main objectives of pre-splitting in open pit mining are: preventing/controlling back-break; controlling excessive ground vibrations; and filtering the effects of explosive gases from production blasting.
