Coal Mining

We,Htoo Han Thit is one of Coal Producer in Myanmar.We do both Open Cast and Underground Mining.Myanmar Coal Mine Production is very less in Amount to support to develop the counting energy and Electric Sector.We hope to do as able as to supply Coal to fill the Demand Amount.
Over 7212 million tonnes(Mt) of hard coal are currently produced worldwide and 810.5 Mt of brown coal/lignite.Coal is mined by two methods: surface or opencast mining, and underground mining.

Coal producers

The largest coal producing countries are not confined to one region – the top five hard coal producers are China,the USA,India,Australia and Indonesia.Much of global coal production is used in the country in which it was produced;only around 15% of hard coal production is destined for the international coal market.

***Myanmar Coal producing quantity is very very less.

Mining methods

Coal is mined by two methods:surface or opencast mining or underground or deep mining.

The choice of mining method largely deponds on the geology of the coal deposit.Underground mining currently accounts for a bigger share of world coal production than opencast;although in several important coal producing countries surface mining is more common.

Surface mining

Surface mining is only economic when the coal seam is near the surface.This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited -90% or more of the coal can be recovered.Large opencast mines can cover an area of many square kilometres and use very large pieces of equipment,such as draglines,power shovels,large trucks,bucket wheel excavators and conveyors.

The overburden of soil and rock is first broken up by explosives;it is then removed by draglines or by shovel and trucks.Once the coal seam is explosed,it is drilled,fractured and systematically mined in strips.The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used.

Mine rehabilitation

Coal mining is only a temporary use of land,so it is vital that rehabilitation of land takes place once mining operations have stopped.In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine,covering the period from the start of operations until well after mining has finished.
