I know a bit about a technique called cut and fill mining. With this method, you drill into the end of a mining chamber called a stope, which is a bit like a tunnel with a brow coming down from the back (what wed call the ceiling). The bottom of

A new iron ore deposit is to be worked by surface mining methods with 15 m benches using 150 mm diameter blastholes. Since the prevailing condition is dry rock, it has been decided to use bulk ANFO with emulsion cartridges as primer. Assume that the overall density of compacted ANFO and the primer as g/cm3 and the powder factor of kg/m3.
(especially iron and copper sulphides) A hole loaded with ANFO detonated prematurely while shot crew were still on the shot. 4. Yael Miron, Blasting Hazards of Gold Mining in SulfideBearing Ore Bodies, Information Circular 9335, US Department of the Interior and US Bureau of Mines, 1992 . Title:
Geologists use many methods to find mineral deposits that will be profitable to mine. Ore deposits can be mined by surface or underground mining methods. Mining provides important resources but has environmental costs. By law, currently mined land must undergo reclamation. This is not true for old mines. Metal ores must be melted to make
#0183;#32;Nevertheless, militarylike shaped charges are sometimes used in the demolition of building and structures and ANFOs characteristics (ANFO is an acronym for Ammonium Nitrate Fuel Oil mixture), though originally developed for use in mining, are also appreciated by the army.

These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe.

Strip mining is ideally applied where the surface of the ground and the ore body itself ar e relatively horizontal and not too deep under the surfa ce, and a wide area is av ailable to be mined in
Mining Mining Surface mining: It has been estimated that more than twothirds of the worlds yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

#0183;#32;ANFO (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial name is commonly pronounced as quot;anfoquot;. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO).. ANFO has found wide use in coal mining, quarrying, metal mining, and civil construction in
ANFO Explosives. A significant problem in the application of ANFO is its use in wet holes. In underground mines since VRM holes are extremely long compared to open pit or surface mining applications, either emulsion or watergel explosives are used. anfo application to mining. blastingmining technologyinfomine, describes the current state of technology of the equipment and technical

iron ore surface mining examples A Brief Introduction to the Types of Surface Mining Methods. A Brief Introduction to the Types of Surface Mining Methods, pit mining is a method in which an ore is removed by digging a pit in the ground, and is used to remove copper, gold, iron, as well as nonmetallic minerals, openpit mining is ideal for ore deposits lying under thin
