Drilling for iron ore. Cindy Hadley is a pit technician for Fortescue Mines. Shes a fieldie working with the iron ore drill rigs. She shares how iron ore is found. She explains how the drill goes down a set distance, for example 30m, and collects a sample every half a metre. She tests the sample of soil to see if the sample is waste or ore - by scratching the surface to look at the
Jan 01, 2015 Iron ore was won by drilling and blasting . As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as dogger) allowing mine drivages to be self-supporting. However, he states that in later years where the mining

To achieve this, in the first step, rock fragmentation, back break, fly rock, specific charge and specific drilling were considered as the decision criteria and their degree of importance was calcu-. lated using the AHP method under a fuzzy environment. Then, TOPSIS and PROMETHEE methods were used to select.

Electric mining drill - Factorio Wiki Know More. The electric mining drill mines out iron ore, copper ore, stone and/or coal, and places it in front of the output tile, on a belt or in a machine/chest that covers the output tile The machine is 33, but mines in a 55 area, extending 1 tile away on each side Mines copper, iron and coal at a rate of 0525/s and stone at a rate of
It takes about 45 mins to complete the drilling process and additional 20 minutes to insert different (Circular bar) bar into the hole already drilled. The process is time-consuming, requires skilled labor. Thus, we are currently looking for alternate and novel methods to get this manufactured and assembled with or without deep-hole drilling.
