Summary Surface mining of brown coal changed Iron mountains basin region fundamentally. Hundreds of millions of hauled masses significantly affected the landscape appearance. Involvement of government authorities and citizens of the affected towns and villages is essential and participation is expected. For proper assessment of the projected mining intent with subsequent remediation of the consequences, processing of 3D models and interactive visualizations options shared with web technology is an important factor. Creation of dump body 3D model, including internal composition, can play important role in various tasks solving, for example in hydrology or geotechnics. High-quality processing of these materials requires use of modern surveying technology, CAD systems and various tools of computer graphics processing.
