This study is accomplished in the coal mining area of Samarinda City, East Kalimantan Province, Indonesia, which is well known to contain a relatively quite large of coal deposit in the city. The study is to analyze the environment economic valuation of the mining activity in the study area until the end of mining, that is during 2012-2034 periode. The economic valuation at this point is carried out by calculating coal depletion, wood depletion and total economic forest value loss. The study results show that of the disturbance area that has not been reclaimed of 156.07 hectares (ha) in 2012, with the level of production of around 1,7 million ton per annumin 2012, we can find that the total gross benefit is around US$ 40 millions, coal depletion around US$ 32 millions, wood depletion around US$ 92 millions and total economic forest loss US$74 ribu, so that total environmental loss is 78,9% of the gross benefit. Furthermore, reclamation activity and cost is a very important factor to affect the environmental total loss during the mining life. The bigger the reclamation activity, the lower the total loss value will be. © Research India Publications.
