A PROPOSAL OF OPEN PIT COAL MINE AT THE NORTHERN PART OF BARAPUKURIA COALFIELD, DINAJPUR, BANGLADESH (2014)

The Barapukuria Coalfield is only production coalfield in Bangladesh with coal deposit area of approximately 6.25 km2. Geologically, the coal basin is a singular syncline in which coal occurs at shallower depth at the northern part and deeper depth at the central part. The Barapukuria coal mine started commercial production of coal by early 2005 with an annual target of 1 million ton per year for 25 years mine life only from the central part of the coal field. But, the coal mine is facing water in rush, land subsidence, roof collapse, methane emission etc. So, the production has stopped several times and it could not achieve annual production target. On the other hand, coal is existed at a shallow depth on the northern part of the field remain untouched because of underground mine design. The present study suggests extracting the coal from the northern part of the Barapukuria coal field by open pit mining method as well as an adequate mine design.
