ABSTRACT
The paper emphasizes the importance of legislation and regulations on safety mining tailings. The first part of the paper presents the current state of technical documents on national and international level. Mines have topographical, geological and mineralogical different features and functions according to management systems, levels of knowledge and understanding of tailings. This leads to the fact that each waste sterile is unique. Applicable laws and regulations of mining tailings differs considerably from one country to another. As we consider, there is presented a review of issues regarding law, management and surveying procedures for mining tailings in different countries. The second part of the paper contains statistics on tailings disposals and the coverage in specific technical regulations. Mining tailings are unfortunately certain risk-bearing works. The size of the risk is given by the relatively high frequency of accidents recorded and produced, as by the magnitude of the consequences, including the disastrous environmental effects that are most evident. Number of accidents recorded worldwide at tailing ponds is particularly high. Some statistics elements on accidents are presented including two examples in Romania. In the last part, the existing legislative framework and the need for a unified legal framework are presented. Drafting carefully and creating heterogeneous regulations it is a solution to various safety issues concerning the tailing ponds.

Keywords: tailing ponds, safety, technical regulations, failure mechanisms, failure probabilities, water management, monitoring, case studies.
