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 …

Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting – The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys (e.g. seismic surveying), aerial surveys, including the taking of samples by low-impact mechanical methods

Drilling for iron ore. Cindy Hadley is a pit technician for Fortescue Mines. She's "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

Mar 11, 2018 · Shrinkage stoping is an overhand mining method that is used for self-supporting vertical ore bodies. In this method, ore is mined in horizontal slices, starting from the bottom to the top of the stope. The broken ore is left in the mined-out stope and serves as a support to the stope walls and a working platform for mining the ore above
