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 had progressed to the dip, this ...

Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food cans to tools.

Updated July 26, 2019. Iron was one of the most basic requirements of the rapidly industrializing British economy, and the country certainly had plenty of raw materials. However, in 1700, the iron industry was not efficient and most iron was imported into Britain. By 1800, after technical developments, the iron industry was a net exporter.
