PT Arutmin Indonesia as a major coal company, has been trying to implement the principles of environmentally sound mining, ie, by carrying out reclamation after coal mining. Erosion that on the area already reclaimed, is the major problems encountered.The purpose of this study was to determine the magnitude of erosion and the magnitude of the danger of erosion (TBE) in various types of land units reclaimed in the PT.Arutmin Senakin. The results of this study is expected to provide useful information to relevant parties for consideration in land reclamation and soil conservation efforts and water, especially in the area of former coal mines. The method used to predict the magnitude of erosion is the Universal Soil Loss Equation method (USLE) is raised by Wischmeier and Smith.The results showed that the amount of erosion occurred in Land Unit I 39.11 tonnes / ha / yr is higher than other land units, but the total hazard ereosi (TBE) at the very extreme of Land Unit V 34.41 tonnes / ha / yr , because it has a value of erosion hazard index (IBE) is more than the Other Land Uni
