Barapukuria Coal field is now producing about one million tons of coal per annum
Development of this coal mine started with help to three Chinese Companies and still the mining is going on (Xuzhou Coal Mining Group Corporation and China National Machinery Import and Export Corporation).Major part of the coal used in the mine mouth 250 MW power plant.
Coal deposits of Bangladesh
In Jamalganj basin, echno-feasibility study for underground mining of this coal was completed in sixties and the expertise in favour of underground mining but it was not materialized. Now different companies are interested in different options in this field. Some are in favour of CBM, some are UCG and some still in underground mining.

About 100 million tons of good qual i ty mineable l imestone at Joypurhat area at depth of 518 meter from the sur face. After detail feasibility study by three foreign companies, a room and pillar method mining scheme with 1700 t h o u s a n d t o n s o f limestone production per annum was formulated in late sixties but it was not materialized.
Limestone deposits of Bangladesh
There is a subsurface hard rock mine in the northern part of the country to meet t h e d e m a n d o f t h e construction materials.Beside these:
There are small glass sand and white clay deposits at the surface to near surface in the nor th eastern par t of the country. These deposits are quarr ied by the local people and sold to the local industries
Hard rock deposits of Bangladesh
After delimitation of sea boundary with Myanmar and India, our Govt. has given emphasis to explore the coastal and sea mineral resources.

Mining policy of the country
By the last quarter of 2010, the Government announced that it had finalized the draft of the National Coal Policy to provide
q Guidance for the development of the coal industry
q Establish coal as a primary fuel for power generation to ensure a reliable source of energy for the country.
q Promote the development, exploration, marketing, and mining of Coal.
Mining policy of the country
The new policy proposed
qWaiver of corporate taxes for contractors and licensees.
q Other incentives included a rebate for duties and taxes applied to the import of machinery to be used for coal mining.
q The policy recommends competitive bidding in order for the Government to grant permits and licenses to contractors .
q Encourages private and public joint-venture investments as well as foreign direct investment
Mining policy of the country
The f i r s t Nat iona l Energy Po l i cy (NEP) of Bangladesh was formulated in 1996 by the Ministry of Power, Energy and Mineral resources to ensure proper explorat ion, product ion, distribution and rational use of energy resources to meet the growing energy demands of the country
Mining policy of the country
The policy was updated in 2004 and included a d d i t i o n a l o b j e c t i ve s n a m e l y to e n s u re environmental ly sound sustainable energy development programmes causing minimum damage to environment, to encourage public and private sector participation in the development and management of energy sector and to bring the entire country under electrification by the year 2020.

Ideas about our future cooperation
qExchanges of scientific and technical information.
qMutual visit and exchange of scientists.qCollaboration on individual research activities.qOrganization of symposia, conferences,
workshops and lectures jointly and qOther forms of cooperation as may be mutually
agreed between the Parties.
Areas of cooperation
Basic Geo-scientific Research 1. Scientific research related to earth evolution and mineral deposits.2. Stratigraphic correlation and standards.3. Geotectonic and deep structure of the continents.
Exploration Methods and Technology 1. Systematic geological, geophysical and geochemical mapping;2. Development of marine geology investigations;3 Hydro-geological investigations
Areas of cooperation Mineral Resources (mainly coal, limestone, white clay, glass sand and heavy minerals) l. Assessment of regional mineral resources and data base construction;2. Mineral and energy resources assessment methods.3. Comprehensive utilization of mineral resources and environmental protection. . Geological Hazards (mainly earthquakes, landslides and river/coastal erosion) l. Investigations and risk assessment because of geological phenomena.2. Monitoring and prevention of hazards because of geological phenomena.3. Evaluation of environmental effects.
Areas of cooperation Geographic Information Systems (GIS) 1. Application of GIS in geoscience.2. Geo-Information Database. .Geo-tourism and agricultural geology.Personnel exchange 1. Training and qualification improvement.2. Co-education talents with universities and 3 Other area of interest agreed upon by the Parties
Prioritization of joint activities
q In the field of Geological Mapping.q Exploration of mineral resources mainly coal
and limestone.q Development of minerals/geological resources.q Geo-hazard assessment and mitigation
approaches.q Capacity building of GSB personnel and lab
facilities.
Conclusions
qChina is a developed country and has vast experience in the exploration and exploitation of the mineral resources.
q Bangladesh may be benefited by the bilateral cooperation between the two countries in the development of geoscience and minerals sector.
qThis could be done by signing Memorandum of Understanding between the relevant institutions of the two countries.
