ECOTERRA - Journal of Environmental Research and Protection www.ecoterra-online.ro 2015, Volume 12, Issue 1 50 Management of mining waste at Valea Arsului dump, Romania Csaba R. Lorinţ, Maria Lazăr, Adrian Florea Mining Engineering Faculty - University of Petroşani, Hunedoara, Romania. Corresponding author: C. R. Lorinţ, csabigeo@yahoo.com Abstract . Vulcan is one of the few active remaining collieries from Jiu Valley, in the Meridional Carpathian Mountains. The Valea Arsului heap stockpiles the tailings from the underground workings from Vulcan colliery. European legislation stipulates the necessity of a waste management plan. The location area of Valea Arsului heap is affected by the subsidence phenomenon due to underground coal extraction. In the paper is presented the stages involved in order to provide the landfill capacity in respect to the subsidence, stability, and environmental issues. Key Words: Jiu Valley colliery, mining waste management, waste dump stability, environmental issues, slide prevention, subsidence modeling. Generalt context . In accordance with the objectives of Community policy on the environment (EUR-Lex 2014), it is necessary to lay down and apply minimum requirements in order to prevent or reduce as far as possible any adverse effects on the environment or on human health which are brought about as a result of the management of waste from the extractive industries, such as tailings, waste rock and overburden and topsoil provided that they constitute waste. Regional settings. Vulcan is one of the few active remaining collieries from Jiu Valley, a hard coal mining basin located in south west of Romania (Buia & Lorinţ 2010), (Figure 1), in the Meridional Carpathians Mountains. Figure 1. Location of Jiu Valley on Romanian map. The Vulcan colliery is located in the central part of Jiu Valley hard coal mining basin (Figure 2). Currently, the mining activities in the Jiu Valley are carried out under the
