The tailing flow generated after dam failure will evolve into Geo-hazards like debris flows. Therefore, it is of great significance to study the evolution and influence range of tailing flow for disaster prevention and mitigation. Physical model experiments and numerical calculation are two major methods in Dam-failure research. These two methods can verify and complement each other, because the former can modify parameters of the latter and the latter can expand the research scope. In this study, a proposed tailing dam was simulated and calculated by using physical model experiment and simulation (Ramms). The erosion process of the dam body of the tailing flow was monitored by the model experiments. The numerical calculation parameters were adjusted to make the results closer to the actual conditions. This study aim to verify the reliability and effectiveness of the debris flow Ramms based on Voellmy model in dam failure simulation. The experiment showed that the velocity (Vmax =38.3 m/s), submerge area (Smax=0.558 km2) and the deposition depth (Hmax=36 m) of the tailing flow. It reflected that the Voellmy model can predict the flow state of tailing flow in the physical model experiments. So it can provide theoretical support and technical reference for the design and management of tailing dam.

The construction of a surface mine always involves the necessity of accessing deposits through the removal of the residual overburden above. In the beginning phase of exploitation, the masses of overburden are located outside the perimeters of the excavation site, on the external dump, until the moment of internal dumping.In the case of lignite surface mines, these dumps can cover a ground surface of several dozen to a few thousand hectares. This results from a high concentration of lignite extraction, counted in millions of Mg per year, and the relatively large depth of its residual deposits.Determining the best place for the location of an external dump requires a detailed analysis of existing options, followed by a choice of the most favorable one.This article, using the case study of an open-cast lignite mine, presents the selection method for an external dump location based on graph theory and the A-star algorithm. This algorithm, based on the spatial distribution of individual intersections on the graph, seeks specified graph states, continually expanding them with additional elementary fields until the required surface area for the external dump -defined by the lowest value of the occupied site -is achieved. To do this, it is necessary to accurately identify the factors affecting the choice of dump location. On such a basis, it is then possible to specify the target function, which reflects the individual costs of dump construction on a given site. This is discussed further in chapter 3.The area of potential dump location has been divided into elementary fields, each represented by a corresponding geometrical locus. Ascribed to this locus, in addition to its geodesic coordinates, are the appropriate attributes reflecting the degree of development of its elementary field. These tasks can be carried out automatically thanks to the integration of the method with the system of geospatial data management for the given area.The collection of loci, together with geodesic coordinates, constitutes the points on the graph used during exploration. This is done using the A-star algorithm, which uses a heuristic function, allowing it to identify the optimal solution; therefore, the collection of elementary fields, which occupy the potential construction area of a dump, characterized by the lowest value representing the cost of occupation and dumping of overburden in the area.The precision of the boundary, generated by the algorithm, is dependent on the established size of the elementary field, and should be refined each time by the designer of the surface mine.
