Abstract. On bauxite mining spoils in central Greece three replicate field trials, with (a) hydroseeding, (b) plus straw mulching, (c) plus plastic net fixing and (d) plus asphalt fixing, were executed and vegetation cover, number of plants and biomass production measured during three consecutive years. It was found that hydroseeding alone gave poor results but slowly improved with time.
A 12stope extraction sequence with a discontinuous strike slot approach is depicted in Figure 3. This method uses primary, secondary, and tertiary stopes designed with a stress shadowing and orebody abutment retreat to manage induced stresses with the assumption that the major principal stress is normal to the long axis of the deposit in question .
mining companies of a percentage of the annual payroll in skills development (excluding the mandatory skills levy); and sustainable development and growth of the mining industry (ibid: 3335). These commitments do not overtly prioritize Hamp;S, although
sequence concept and how other sequence options are located within this range. The opportunity to identify the value of the best option is an excellent reference for a mine planner when they are comparing different alternatives for a sequence. If a sequence value is close to the best case, then there is little opportunity to improve the sequence.

Mine development may involve many activities such as: The preparation of the mine site by clearing trees and blasting rock; The construction of mining facilities such as head frames, administration buildings or mechanical shops
It should be noted that over the last three decades lignite mining in Greece has been taking place exclusively via surface mining. The only exception is a private underground exploitation that has

Project development: timing is everything. By Rodney Nelson . Global Mining Leader Projects KPMG in Australia Few mining companies possess either the engineering strength or the will to build a mine completely independently. The engineer, procure, construct (EPC) model is an increasingly popular approach to oil, gas and infrastructure
Air pollution is a major problem in the world today, causing undesirable effects on both the environment and human health and, at the same time, stressing the need for effective simulation and forecasting models of atmospheric quality. Targeting this adverse situation, our current work focuses on investigating the potential of data mining algorithms in air pollution modeling and shortterm

This type of data mining can reveal various aspects such as distance and topology which is mainly used in geographic information systems and other navigation applications. Time Series and Sequence Data Mining. The primary application of this type of data mining is study of cyclical and seasonal trends.

In the early 19th century, the mining industry and Industrial Revolution stimulated the rapid development of the stratigraphic column quot;the sequence of rock formations arranged according to their order of formation in time.quot; In England, the mining surveyor William Smith, starting in the 1790s, found empirically that fossils were a highly effective means of distinguishing between otherwise
