Open cast mining is mines that are dug on hilly areas. It is quick easy way of providing coal but it damages the wildlife and can be quite dangerous. The way open cast mining is carried out is that they stay on the same ground level when digging. This is done by moving the dug out soil along so slowly more area has been dug out. This will continue until all the coal has been removed and then the mine will be filled up again and left to grow naturally.
Open-pit mining is the extraction of mineral ores or solid fossil fuels that occur in seams or strata that are located near the surface. It involves the removal of surface overburden material, and the extraction of ore bearing material, all occurring at the surface, not in underground shafts. See related links below for a picture of an open pit mine.
There are some technological methods that are used in mining are:Open-cast mining : Open-cast mining is done when a mineral is located very close to the surface. In the open-cast mining, different minerals are taken out by removing the surface layer. Open-cast mining is famous for coal mining in India and many other countries.Shaft mining : The word 'shaft' refers to deep bores. In the shaft mining, deep bores are created to reach mineral deposits. This is because, these deposits lie at great depths. Petroleum and natural gas are extracted by shaft mining.
The two types of mining are Open-cast mining and Underground mining. Underground mining is further divided in to Adit mining and Shaft mining.

Open Pit Mining
Blasting is the use of explosives to break rock as one step in mining. Sometimes explosives are used to break AND move rock to one side- to permit the mining of what was under the rock. THAT is cast blasting. Rock is cast aside.

THERE ARE DIFFERENT TYPES OF MINING SUCH AS SURFACE MINING,open cast mining, strip mining,alluvial mining,quarrying mining,underground mining,and drilling
The two types of mining are Open-cast mining and Underground mining. Underground mining is further divided in to Adit mining and Shaft mining.
What are two main types of mining and how do they differ? Open cast mining, and underground mining. The reason they differ, is because underground mining is where they create shafts that lead to ore beds. Open cast mining, is the opposite of underground mining. I really hope this answer is useful! I love to help people get better at science. I hope I helped you guys! Bye.
