The coal mine is developed through open cast mining. We had contracted out trial production to several independent contractors in 2006. In 2007, the company decided to focus on detail exploration efforts in 700 Ha areal while preparing for a large scale mining operation.

The coal mine is developed through open cast mining. We had contracted out trial production to several independent contractors in 2006. In 2007, the company decided to focus on detail exploration efforts in 700 Ha areal while preparing for a large scale mining operation.

The commercial operation started in 2009 and is currently being carried out by a reputable mining contractor with vast experience in mining service industry. The company has earned the trust of many top tiered coal producers. The company’s management team comprises of former senior executives of PAMA. The scope of work also includes the removal of overburden, the loading and transportation of coal from the mine site to the processing plant and stockpiles, and maintenance of the mine's haul roads.

The production consists of several steps. First the site is fenced off, and motor scrapers carefully remove topsoil and subsoil.  Afterwards, the earth overlying the coal seams (called the overburden) are excavated. This task is started by dozers, but as depth and hardness increases, mechanical shovels with dump trucks are required. The thicker seam has to be ripped with dozers before being loaded by 30 ton excavators. About 3,3 tonnes of overburden are removed for every ton of coal recovered. As excavations approach the coal seams, smaller machines are used to remove the overburden nearest the coal. 

The overburden from the coal mine is loaded by 40 ton excavators, hauled by 30 ton capacity of dump truck through a 400m road to the waste dumps. The thicker seam has to be ripped with dozers before being loaded by 30 ton excavators. Once the coal has been extracted, the overburden is replaced to the ideal contours and the subsoil and topsoil are re-spread. The company strives to restore mined land to a variety of uses mostly beneficial to the local community. Most land is returned to agriculture use, but subject to planning permission, restoration to forestry, recreation areas, industrial or residential development is possible.


Quality Assurance

PT. Anzawara Satria employs stringent Quality Assurance practices throughout the coal production chain. From initial exploration, throughout production process until the coal is loaded on to a customer's barge or vessel, coals are sampled and tested at each stage of the coal chain as follows:
  • Initial drilling.
  • Channel sampling.
  • Ex crusher (ROM).
  • At the stockpile awaiting barge.
  • Loading onto customers vessels (independent sampling and analysis).

This ensures the delivered products meet the contractual specifications.
