Mining is a multibillion dollar industry obviously because of its colossal role in industrialization. It can be done in two ways—creating an open pit or an underground operation. Open-pit mining is ideal when ground inspection suggests that there’s a huge volume of ore deposit under the mining site. Underground mining can be done if the ore deposit is concentrated in deeper areas. The latter is a more popular option, especially if the mine site is surrounded by structures or close to a community.
In underground mining, shafts are developed to provide workers and machines with access to the ore underneath. Once a shaft is built, mine skips and cages will be installed for the transportation of extracted ore, equipment and employees. The ore will be drilled and crushed to be easily conveyed through the skips. After extracting all ore deposits, the shaft will be closed by filling with the overburden produced during excavation.
