Diamer-Bhasha dam



Diamer-Bhasha Dam is the name of a dam that has been planned in the Northern Areas of Pakistan on the River Indus. Diamer Basha Dam Project will be the highest Roller compacted concrete Dam in the world, height of 272 meters spillway with fourteen (14) gates.


Total cost & capacity of the project


The cost of the Diamer-Bhahsa dam is $12.6 billion (November,2008) and it will have a storage capacity of 6,340,000 acre feet (7.82×109 m3) as against the earlier proposed 7,340,000 acre feet (9.05×109 m3). However, it will have a power generation capacity of 4,500 megawatts.



Merits


Availability of about 6,400,000 acre feet (7.89×109 m3) annual surface face water storage for supplementing irrigation supplies during low flow periods. Employment opportunity, particularly to the locals, during the construction and operation. Reduction of dependence on thermal power, thus saving foreign exchange.



Demerits


However, the construction of the dam will cause the sinking of over 50,000 ancient rock carvings, destroying precious archaeological evidence of inhabitation of the area since the Epipaleolithic and Neolithic eras. Moreover 38 villages and 2800 families will be affected from this project.



Conclusion


However this project has some demerits but keeping present problems in mind the project has became a serious need as Kalabagh dam has many political issues....

Pakistan and Nuclear Power



Pakistan Atomic Energy Commission has claimed to have discovered around 1,000 uranium favourable sites, which could provide the required fuel for its proposed nuclear power plants. Four of the 1000 sites were being mined and another nine with potential uranium reserves had been identified as very promising, Dawn quoted officials as saying. “The effort was rewarded with the discovery...


Mines


The Wahi Pandi, Karunuk (Sehwan), and Rehman Dhora (Aamri) mines in the, Kirthar Range, Sindh and the Shanawah Deposit, Karak in Khyber Pakhtunkhwa province are being opened up to meet Pakistan's rising need for uranium, which these sources are issuing at a ore grade: 0.04% Uranium mineral purity rate. The Baghalchur site has several abandoned mines and is now being used as a industrial dumping ground. The Mianwali site also has several mills and processing plants to.[11] Uranium is being mined or refined at the Miniawali site.


Baghalchur (Urdu: بغلچور) is small town in Dera Ghazi Khan District, Punjab, Pakistan. Baghalchur is the site of abandoned Uranium mines now being used as a nuclear dump. The resident of the area along with several Pakistani environmentalist groups are bitterly opposed to the nuclear dump being used by Pakistan Atomic Energy Commission (PAEC) have asked the government to invest in better techniques in the disposal of nuclear waste materials.


Output


Pakistan produced about 45 tonnes of Uranium in 2006.


Conclusion


Pakistan is is self sufficient in it’s need of nuclear power only if we explore this sector our electricity crises can be finished for ever….

The Sandak Project


Sandak Project

By producing 7.746 tonnes of gold during the last five years – 2004 to 2008 – Pakistan has joined the ranks of gold producing countries.


According to the data available with the Sandak Metal Limited – during the last five years – Pakistan has produced 86,013 tonnes of copper, 7.746 tonne gold and 11.046 tonne silver, besides the production of 14,482 tonnes of magnetite concentrate (iron), bringing in a total of $633.573 million.


Just because we lack the extraction technology we have to sell these minerals in their raw form to the others countries who extract the end product and earn millions from it. We need more industries like Sandak in Balochistan for the utilization of the minerals found there....


A little country like singapore exports more then Pakistan and they have no raw materials, they import them and then turn them into products and export them, in Pakistan we have almost everything and can make these products alot cheaper then these countries in the far east who exports billions and billions every month at high rates....


When will our govt. wake up???

Alterantive Power Sources


Thar Coal Reserves

Pakistan has fourth largest coal reserves in the world but it is importing 2.5 million tons of coal per annum for cement industry.


Coal -the black gold, is found in all the four provinces of Pakistan. Country has huge coal resources, about 185 billion tons, out of which 3.3 billion tons are in proven/measured category and about 11 billions are indicated reserves, the bulk of it is found in Sindh province.


These coal reserves can produce electric energy in extremely low cost and can fulfill our need of electricity for decades.


But our failed Government has never paid attention to this section.
