There are four main mining methods underground open surface pit placer and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments.

In general this type of mining technique is used for extracting coal however it is applied to other material types i.e. from metals to minerals. Based on where these supplies rest in relation to the surface of the earth this cut may be the single excavation method used on a project or may be the first of many techniques in use.
In India around 92 of the coal is produced by opencast mining method Table 1. If do mestic coa l pro duction cont inues at 5 increasing rate the extractable r eserve will last for 45 years.
In India the number of operating opencast mines is steadily increasing as compared to underground mines. It is due to low gestation period higher productivity and quick rate of investment. On the contrary opencast mining attracts environmental concerns such as solid-waste management land degradation and socio-economical problems.
