Coal mining contractors and their operations.

Overview of coal mining industry

Involvement of the private sector especially foreign investors in coal mining began in Indonesia early 1980 when the government of the country invited foreign investors to develop coal reserves especially in Kalimantan.

Rapid development began of the country's huge coal reserves after the involvement of the private sector including foreign and domestic investors. Hundreds of contracts under the Contract of Work (KK) scheme--from Generation I to Generation IV and Coal Mining Development Agreement (PKP2B) have been signed over the past three decades.

Large numbers of heavy equipment sets are used in coal mining in the process of removing soil and drilling as well as transport of coal. The mining sector, therefore, is the largest user of heavy equipment in the country. The types of heavy equipment used in coal mining are mining trucks, excavators, etc.

The brisk development in coal mining has pushed up demand for heavy equipment. In Indonesia, heavy equipment is used by coal mining companies or coal concession holders as well as coal mining contractors.

Coal Mining Areas

The main coal mining areas in the country are Kalimantan and Sumatra. In Kalimantan, coal reserves are found in the provinces of East Kalimantan and South Kalimantan. In Sumatra, coal reserves have been found in West Sumatra, South Sumatra and Bengkulu.

East Kalimantan is the largest producer among the provinces accounting for around 55.4% or 406.6 million tons of the country's total production of 773.4 million tons of coal in the 2004-2009 periods. The second largest producer is South Kalimantan contributing 38.8% or 284.7 million tons to the total production in the same period.

Sumatra has small contribution. South Sumatra contributed 5.7% or 41.6 million tons and Bengkulu 501,000 tons or 0.1% of the total production in the same period.

Coal Production

The country's coal production has continued to increase in the past several years. In 2005, the production was recorded at 142. 3 million tons. In 2006, the production surged 20.8% to 171.8 million tons--or the highest growth in the past several years. The production grew further by 10.1% to 193.5 million tons in 2008 and by 17.6% to 227.2 million tons in 2009.

The production was boosted by booming in coal market. Coal came as a cheap and most easily available alternative source of energy amid the soaring prices of crude oil lately.

Open pit mining dominates coal mining systems

Open pit mining is the only system used for coal mining in Indonesia because of the position of the coal reserves. Open pit mining needs heavy equipment like excavators, bulldozers, loaders and dump trucks of large size.

Prospects of business in coal mining still encouraging

The prospects of business in coal mining in Indonesia are very encouraging as the country still has large coal reserves yet untapped.

Meanwhile demand for coal as a source of alternative energy amid the soaring price of oil is growing. In Indonesia , coal is growing in demand especially to feed coal-fired power plants. The country is building coal-fired power plants with a total capacity of 10,000 megawatts under its first fast rack development program in the electricity sector.

Major coal mining companies

There are 60 companies operating in coal mining industry, but production is dominated by 7 producers. The 7 producers accounted for 70.4% or 160.3 million tons of the country's total production 227.5 million tons in 2009.

The seven companies are PT. Adaro Indonesia, PT. Kaltim Prima Coal (KPC), PT. Kideco Jaya, PT. Arutmin, PT. Berau Coal, PT. Indominco, and PT. Pertambangan Bukit Asam (PTBA). Adaro was the largest producer with production of 40.6 million tons in 2009, followed by Kaltim Prima Coal (KPC) with production of 38.1 million tons, Kideco with production of 24.7 million tons.

PT. Adaro Indonesia

Adaro has the world's largest single coal mine. Its coal mines are located in Tabalong and Balangan, in South Kalimantan with reserves of 3.4 billion tons (JORC Compliant).

Adaro is a holder of contract of work (CoW) of the generation I valid until 2022. Its production capacity was 48 million tons / year in 2009 including 16.4 million tons of its subsidiaries PT. Saptaindra Sejati (SIS), which operates mainly in as coal mining contractor. PT SIS has the capacity to remove 115 million cubic meter of overburden and has 6 clients among coal concession holders in South and East Kalimantan including Adaro.

Adaro's coal production totaled 40.6 million tons in 2009, up from 38.5 million tons in 2008.

Adaro plans to increase its annual production to reach 80 million tons in 2014. It has 37.8 kilometer over land conveyor with a transporting capacity of 40 million tons of coal per year.

Adaro through its subsidiary PT. Alam Tri Abadi plans to acquire 25% stake in each of 7 Indonesia Coal Projects (ICP) in Maruwai from Australia'sw BHP Billitons. The acquisition is estimated to cost US$ 335 million. Adaro will cooperate with BHP Billitons which retains a 75% stake in developing the 7 coal mines in Maruwai, Kalimantan.

The seven projects are PT Maruwai Coal, PT Juloi Coal, PT Kalteng Coal, PT Source Barito Coal, PT Lahai Coal, PT Ratah Coal and PT Pari Coal.

PT. Kaltim Prima Coal

In 1978, the Indonesian government began to invite bidders among foreign investors to development and exploit coal reserves in the country offer investment. A consortium of British Petroleum and Rio Tinto was awarded a concession of 7,900 hectares in 2 blocks along the eastern coasts of Kalimantan.

PT. Kaltim Prima Coal is one of coal mining companies in East Kalimantan owned by PT. Bumi Resources. KPC was acquired by Bumi from British Petroleum and Rio Tinto on 10 October 2003.

PT Berau Coal secured the CoW from the government in 1983 with mining areas in northern part of East Kalimantan called Berau. The concession covers a total area of 1,200 hectares consisting of 6 areas.

Coal production of Berau comes from a number of areas in its concession including Lati (1994), Binungan (1996) and Sambarata (2001). The proven reserve in Lati totals around 745 million tons, and in Binungan of blocks 1-4 and blocks 5-7 totals 300 million tons. Meanwhile, explorations are still in progress in Kelai and Punan areas to determine the strength of the reserves.

The mining systems in all areas in the concession of Berau Coal are open pit mining using trucks, excavators, loaders and bulldozers to remove the overburden and mine the coal. The mining is handled by a number of contractors.

Perusahaan Tambang Batubara Bukit Asam (PTBA)

The company dates back to the Dutch colonial time with an embryo starting operating in 1919 in open pit mine.

The asset was confiscated by the government of Indonesia after his country gained independence and put the mine under PN Tambang Batubara Bukit Asam. In 1981, the company was renamed PTBA.

The installed production capacity of PTBA is 20 million tons per year. In 2010, PTBA plans to produce 10.8 million tons of coal, up 4.8% from 2008.

Overview of coal mining contractors

Mining work at coal mines in Indonesia is largely handled by contractors. Coal mine concession holders hand over the work to contracts for cost efficiency saving them from buying expensive heavy equipment.

Contractors offering mining service in coal sector are generally experienced in heavy equipment operations. Among them are subsidiaries of heavy equipment distributors or plantation companies such as PT. Pama Persada Nusantara, which a subsidiary of PT. United Tractors Indonesia, the sole agent for Komatsu heavy equipment; PT. Bukit Makmur Utama Mandiri, which was formerly a contractor opening plantation areas using many units of Hino trucks.

Mining contractors are the main users of heavy equipment. Coal mine concession holders have relatively few units of heavy equipment.

Currently there are 116 companies operating as mining contractors in Indonesia. They offer heir services to 60 coal producers. Among the main contractors are PT. Darma Henwa, Tbk, PT. Pama Persada Nusantara, PT. Thiess Contractors Indonesia, and PT. Bukit makmur Utama Mandiri.
