The bit strikes the rock and rotates at a certain speed to move the position of carbide insert or plate to another part of rock; the typical bit blow frequency is 2000-3000 blows/min and the rotation speed is 50-150 revolutions/min. Typical percussive drilling bits with carbide plates or …

Doing cut risk assesments with all sections involved in order to minimize risks that might occur or that can be expected for each mining bench.
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.
Ore-reserve estimates are based upon the results of exploration and development and analyses of the samples derived therefrom. Unless a deposit is fully developed (and even then to a lesser degree), certain assumptions have to be made regarding the continuity and grade of ore between exposed faces or drill holes that have been sampled.
by benching. Standard crawler rigs are used for drilling vertical holes and for conventional bench blasting. Horizontal drilling and "flat" benching are more practical alternatives because the same drill jumbo can be used for both topheading and drilling flat bench holds. The blasted ore is loaded at the muckpile with diesel-driven front-end ...
Understanding Iron Ores and Mining of Iron Ore. Iron (Fe) is an abundant and a widely distributed element in the in the crust of the earth, constituting on an average ranging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Its supply is …
Working on 10 m-high benches, they drill 165 mm blast holes in lime/calcrete, banded iron ore formations and manganese ore. The drilling pattern is 4 x 3.5 m and the holes are drilled at angles of 70 and 90 degrees, 14 m deep with one meter of subdrilling.

ore grade profile of each bench. The data are stored in the computer where they can be attached to the blast hole coordinate file. The attached plot shows a typical magnetic profile of a blast hole. Massive beds often show up as relatively uniform areas. Hole collars show very low values due to fluting and resulting increased
Iron Ore. The generation of nitrogen oxides within post-blast gases (commonly referred to as "fume") has become increasingly important for mines from a safety, productivity and regulatory standpoint, particularly those in populated areas. In response to industry demand, Orica has developed a complete Fume Risk Reduction protocol that takes ...

In the banded iron formation-hosted iron ore deposits in the Hamersley Range of Western Australia, the stratigraphic boundaries are generally modelled using data from exploration drilling. Accurately identifying the locations of boundaries is important when modelling and mining ore deposits. Exploration drilling typically has a coarse horizontal spacing (~ 50 m), resulting in …

To drill with RC but vertically is a missed opportunity that does not optimise its ability to vastly improve sample quality with angled holes alone. Sampling data bench by bench cannot often keep up with the production demands to mine. The last bag sample on the bench leaves for the lab but the production superintendent is ready to blast.

Sublevel Open Stoping originated in the early 1900's in iron ore mines in Michigan, USA. It was developed over the years from a method originally known as short hole bench and train mining.Generally a large scale open stoping method, it is often referred to as long hole or blast hole stoping. A Typical Sublevel Open Stoping Operation.

Forming a sequence plan for a machine to travel to a series of specified locations is described. An initial cost table ( 414 ) and a pattern of locations ( 412 ) is inputted to a Sequential Ordering Problem (SOP) solver ( 402 ). The resulting sequence ( 410 ) is processed by a motion planner ( 404 ) to derive by a motion planning procedure a plan of machine motions through the sequence.
