Design of an Effective Illumination System for an Opencast Coal Mine

The illumination survey was performed in mine-A, a mechanized opencast coal mine project, of a major public sector coal company located in the Korba area, Chhattisgarh, India. The mine had a total area of 6.3 sq. kms and mineable coal reserves of 57.5 million tons. The annual coal production is 2.5 million tonnes and average coal Coal is one of the most essential resources of a country. It is widely used for power generation and as a raw material in the industries. India ranks third in coal production. However, the country has to import Underground and Opencast Coal Mining Methods

The main advantage in open-cast mining is that it is much more safer and, at the same time, the rate of coal production per day is at least two to three times more than that in the underground. Moreover, in the open castElectrical Distribution, Protection and Controls in Mines

The open-cast coal mining is complex and demanding industry which needs high operational efficiency [9]. Historically, mining has also been one of the most dangerous work environments [7,4].Open pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/day and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of Opencast Mining Method PDF Coal Mining Surface Mining

Development and Application of Blast Casting Technique in

Blast casting is a high-efficiency technique applied in surface mines for overburden removal and results in stripping cost savings. According to ballistic theory and center-of-mass frame basic movement principles, key factors influencing blast casting effect were analyzed, which include bench height and mining panel width, inclined angle of fields of mining and handling of coal, ore and other minerals, as well as removal, transport and dumping of overburden. Our machines and systems have proved to be reliable in mining hard minerals, even under extreme operating conditions. oPEn caSt MInInG EquIPMEnt The extensive know-how of our highly qualified engi-open cast mining equipment TAKRAF GmbH

Lesson 7.3: Mechanical Surface Mining Methods Open Cast Mining

Open Cast Mining. Open cast mining is usually associated with coal or other tabular deposits that are more or less flat-lying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut.OPENCAST (STRIP) MINING Introduction: Opencast (strip) mining is a surface exploitation method, used mainly for coal and other bedded deposits, which resembles open pit mining. However, it differs in one unique respect: the overburden is not transported to waste dumps for disposal but cast directly into adjacent mined-out panels.Lecture-Opencast Mining Methods.pdf OPEN PIT MINING
