Development Of Barapukuria Coal Mining.

Development at the time of Project:

In 1985 Geological Survey of Bangladesh (GSB) discovered high quality bituminous coal spread over an area of 6.68 Square Kilometers at a depth ranging from 118 to 509 meters in Barapukuria under Parbatipur upazilla in the district of Dinajpur. During 1987-1991 a UK based company M/S Wardell Armstrong carried out the Techno-Economic Feasibility study on this coal reserve under ODA financial support. Based upon the  Wardell Armstrong report, a contract was signed  between China National Machinery Import & Export Corporation (CMC) and Petrobangla with a view to develop an underground mine having a caspacity of 1.00 Million Metric Tonnes of coal per annum. After substantial completion of the mine construction work, the mine was taken over from the construction contractor in September 2005.

Contract And It’s Activities

1st M&P Contract & it’s Activity:

A Management & Production (M&P) contract amounting to US$ 82.30 Milion was signed with CMC-XMC Consortium on 4 June 2005 for the purpose of ensuring the production activities of the mine. According to the agreement M&P contractor entered into the commercial production on 10 September 2005 and as the contract was expired on 10 August 2011, all the works associated with it were successfully concluded. On this agreement, the contractor acheived the production 36.50 Lac metric tons against the target of 47.50 Lac metric tons.

2nd MPM&P Contract & it’s Activity:

Through an international bidding process, a “ Management, Production, Maintenance and Provisioning Services” (MPM&P) contract was signed with XMC-CMC Consortium on 10 December 2011 for the purpose of ensuring the production activities of the mine and the contract expired on 10 August 2017. According to the contract period of 72 Months, the contractor acheived the production 55.04 Lac metric tons against the target of 55.00 Lac metric tons.

In addition to the production of coal, the contractor provided a set of LTCC equipment, all materials and spare parts for development and production activities, constructed 5 hydrogeological boreholes for collecting of different types of geological and hydrogeological data/information, supplied and installed two generators of 3.5 MW and 3.38 MW respectively, established 3 high powered pumps in underground, a deep tube well in Surface to cope the increased demand of cooling water etc.

3rd MPM&P Contract & it’s Activity:

Through an international bidding process, a new MPM&P-2017 contract was signed with XMC-CMC Consortium on 08 July 2017 for the purpose of ensuring the production activities of the mine. This contract is effective for 48 month, which has been effective from 11 August 2017. Within the contract tenure, the contractor shall produce 3.205 milion metric tons of coal. As per contract provision, they shall supply one set of LTCC equipment, all spares and consumeables required for production and development, supply and install 3 new generators having 3.38 MW capacity of each, new pump houses and sumps at -430m level and -500m level, install pipe shaft, construct 6 hydrogeological bore holes to produce coal from the third slice of the central part of the mine, procurement of nitrogen plant to ensure the underground favourable working condition and contain hazardous gas as well.

The contractor has started their work as per schedule time according to the agreement. At the first year of the contract, the contractor acheived the production of 0.647 milion metric tons against the target of 0.819 milion metric tons, which is 79% of the target. A total of 10.02 milion metric tons of coal was produced from the begining of the mine upto March 2018. On the other hand, 0.78 milion metric tons of coal was produced against the target of 0.82 milion metric tons by March 2018. We are hopeful that we will be able to fulfill our target within the stipulated time. Moreover, road way development has completed 2,888.20 meter by March 2018 against the target of 2,500 meter, which is 15.5% more than the target.

According to the agreement the consortium has started to construct water sump and pump house in underground. Already road and pavement construction has been completed to get access to the one borehole site for the purpose of constructing 6 hydrogeological bore holes. Other tasks of the contract are expected to begin as per schedule.

At present coal is being  produced from 1210D face. From this face 4.70 lac metric tons of coal is produced against the target of  4.30 lac metric tons. It is expected that coal production will end on 15 may 2018. Development work of the 1314 face is going on as the first face of third slice. It is expected that coal production from this face may start from July 2018.

Slice And Method Of Coal Production

Coal Produce from 1st and 2nd Slice:

From the coal basin discovered at Barapukuria, 6 seams have been determined. An average thickness of the 6th seam is 36 meters. Commercial coal production from the first slice of the central part started from 10 September 2005which was successfully completed on 14 February 2012. During this time, coal has been extracted from 11 longwall faces fully and from 1 longwall face partially (long wall 1110 face). From the first slice 41.67 lac metric ton coal was produced.

On completion of the first slice, coal production was started from the second slice on 15 March 2012. 58.60 lac metric tons  of coal was produced from 10 faces of the second slice by March 2018. It is expected that the coal production from 1210D longwall face will end on 15 May 2018. Development work of the 1314 face is going on as the first face of the third slice. It is expected that coal will be produced from this face by July 2018.

LTCC Method:

To upgrade the longwall mining system, Longwall Top Coal Caving (LTCC) method was adopted on 08 May 2013 for extraction of coal from Barapukuria coal mine. Productivity has been enhanced significantly after introduction of this method. Under this method, coal is extracted at a higher rate by mining out slices of 3 meter cutting height from front AFC and those of 2 meter caving height from rear AFC. Coal has been extracted from the whole of 6 faces and partially from 2 faces by LTCC method. At present coal production is in progress under this method from face 1210D. After introducing LTCC method, coal worth 4,500 metric tons is extracted per day on an average.
