Drilling and blasting WikiMili, The Best Wikipedia Reader
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction The result of rock blasting is often known as a rock Lecture Overview Introduction Pit Geometry Interaction deposit geometry Design and management Overall process Interaction of distinct operations Machinery – Drill Rigs, Loaders, Excavators etc General appraisal History From ancient times to Blasting Drilling of Open Pit Mining Hardrockdrills Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive systemOptimized design of drilling and blasting operations in
DRILLING AND BLASTING DESIGN BASED ON
DRILLING AND BLASTING DESIGN BASED ON INVARIABLE MINING PARAMETERS distribution in conditions of “Kuznechnoe” openpit mine Conformity of logarithmic variance (~10) between drilling chips, blasted rock and natural block size shows that statistical analysis characterizes In open pit mining where rock is hard such that,it requires drilling and blasting techniques to be applied for it to be mineable, the overall costeffectiveness of the production operations requires that drilling and blasting be optimized Mining costs for unit operations which includes loading, hauling, crushing costs reduce with increasing rock fragmentation sizes Quality of blast results in open pit bench blasting plays a key effect on the efficiency and cost of drilling and blasting and subsequently mining Optimization of blasting design parameters on open pit Drilling and blasting play vital roles in opencast mining These operations not only affect the cost of production directly but as well and significantly, the overall operational costsOptimization of drilling and blasting operations in an
