SURFACE MINING

SURFACE MINING

UNIT 1-Role of surface mining in mineral production in India, Elements of surface mine planning-height, width, slope, Overall and ultimate pit slopes, Stripping Ratios and Cut off grade.
OPENINGS UP OF DEPOSITS-Different system of openings of deposits, Site preparation, Box cut, Formation of benches, Haul roads.


Along with 48.83% arable land India has significant sources of coal (fourth-largest reserves in the world), bauxite, tiranium ore, chromite, natural gas, petroleum and limestone.According to the 2008 Ministry of Mines estimates: 'India has stepped up its production to reach the second rank among the chromite producers of the world. Besides, India ranks 3rd in production of coal & Lignite, 4th in iron ore, 5th in bauxite, 7th in manganese ore and 8th in aluminium.
Indian mines majorly accounts the future prospective of surface mining.

With this vast knowledge of surface mining students can perform well in their semester examinations.
Practice-Perform-Progress.

Wireless Blasting in Underground Mines

Wireless Blasting in Underground Mines We all know that the entire Mining Industry is moving rapidly towards an automated future systems and it is constantly changing & challenging field for the upcoming future targets too be achieved with safety in the highest priority. Although, Traditional practice of using wired detonators in underground mining has a limited distance of initiation from the blasting face and draw points in sublevel cave mines, which can be replaced with precise, accurate and reliable system developed by the Orica Group. Working:- The system is similar to the signalling of nuclear submarines even while they were hundreds of metres below the ocean.This technology uses low frequency magnetic induction waves to communicate. The signals are generated by a transmitter and received by each primer prior to a blast.The primers are encoded with their group ID and delay time just prior to charging.This data is “stored” in the primer and detonator respectively.T...

Clean Coal Technology

Clean Coal Technology The term Clean coal technology means any technology deployed at a new or existing facility which will achieve significant reduction in air emissions of sulfur dioxide or oxides of nitrogen associated with the utilization of coal in the generation of electricity. Indian systems and technologies adopted are ancient times and case studies acquired that time but now the changing requirements of our nation is basically dropped from 40j/kg to 27.8j/kg over past 50 years. Nowadays Indian policies are changing to the environmental responsibilities. UNIT-1:- Life cycle of Coal, Coal characterization, Classification System of Coal, Rank and Grade of coal, C-H Graph Form this blog students can download unit 1 from here . UNIT-2:-Coal beneficiation--Feed grade dry and wet coal beneficatiben techniques, chemical and biological methods of coal cleaning, coal washing--Objectives and techniques; washability curves. Students can download unit 2 from...
