- the surface soil that must be moved away to get at coal seams and mineral deposits
- load with excessive weight
- burden with too much work or responsibility
- overburden removal and other development and preparation of mineral properties and sites.
- geomechanical, geochemical and flow properties of the reservoir overburden (caprock, seals, porous and permeable horizons) and surrounding formations;
- Exports of very small quantities of products are of no economic significance and are liable to overburden the competent authorities unnecessarily.
- The ability not to overburden tendered contracts, where it was submitting bids to open tender, with the costs related to redundant staff was indeed essential if Tieliikelaitos was to adapt to a competitive market.
- Description of the nature of all the wastes occurring in each prospecting, extraction and processing operation, including overburden, waste rock and tailings, by providing information on the following elements:
- description of expected physical and chemical characteristics of the waste to be deposited in the short and the long term, with particular reference to its stability under surface atmospheric/meteorological conditions, taking account of the type of mineral or minerals to be extracted and the nature of any overburden and/or gangue minerals that will be displaced in the course of the extractive operations;
- In accordance with the objectives of Community policy on the environment, it is necessary to lay down 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 (i.e. the waste solids or slurries that remain after the treatment of minerals by a number of techniques), waste rock and overburden (i.e. the material that extractive operations move during the process of accessing an ore or mineral body, including during the pre-production development stage), and topsoil (i.e. the upper layer of the ground) provided that they constitute waste as defined in Council Directive 75/442/EEC of 15 July 1975 on waste.
