Located exactly in the middle of forest in east Kalimantan, it takes about 6 hours from city of Province, Samarinda, and 8 hours from the Domestic & International Airport Sepinggan in Balikpapan.Sangatta is a large facility of coal mining. Over 80 people of sangatta's citizens are came from outside of Kalimantan..Mostly come from Sulawesi (Celebes), Java and Australia. They all working for no 1 Coal Mining Company in Indonesia (and no 4 in the world), PT. Kaltim Prima Coal.
To go to Sangatta, can be taken by road using a car, or through the air by using an airplane. When using a car, it takes two hours' drive inland from the town of Bontang to Sangata, four hours from Samarinda or six hours from Balikpapan. Meanwhile, if taken through air travel from the airport Sepinggan, Balikpapan, Tanjung Bara to the airport, Sangata, takes one hour.

Procedures and Methods of Mining
The mining process from discovery of an ore body through extraction of minerals, and returning the land back to its natural condition consists of several steps. First, is the ore body invention which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body. to estimate the size and grade of the deposit needs a mathematical resource estimation. This estimation is used to lead a possibility study to determine the economics theories of the ore deposit. This identifies, early on, whether further investment in estimation and engineering studies is warranted and identifies key risks and areas for further work.
The next step is to lead a possibilities study to evaluate the financial viability, technical and financial risks and endurance of the project. This step is when the mining company makes the decision to proceed the mine development or to walk away from the project. This includes mine planning to evaluate the economically recoverable portion of the deposit,
the metallurgy and the abillities of ore recovery, market and payments of the ore concentrates,
engineering matters, milling and infrastructure costs, finance and equity requirements and an analysis of the mine which proposed from the initial excavation through to the reclamation.
Once the analysis determines a given ore body is worth recovering,
development begins to build an access to the ore body. The mine buildings and processing plants
are built and any necessary equipment is obtained. The processes of the mine
from recover the ore begins and continues as long as the mining company finds that their economical condition is at stable state. Once all the ore that the mine can produce good profit is recovered, reclamation begins to make the land used by the mine suitable for future use.
