This paper seeks to quantify the value that may be lost if closure planning is not adequately considered in life of mine planning and the difference in the mine plan between scenarios that adequately consider closure costs and those that do not.
At different stages of non-periodical ground pressure and periodical pressure, as the differences in mining height, advance speed and distance from the support tip to the coal wall, the spalling depth and spalling ratio were different at a LLTCC coal mining face (Yan 2008; Yin et al. 2008; Zhang et al. 2010).
New mine soils had a slightly higher bulk density than the native soils due to the differences in mining method rather than pedogenic processes.
With this approach, differences in mining operation resulting from the accessibility of the coal and the amount of overburden generated in different regions can be taken into account.
These results must be interpreted with caution due to differences in mining practices that may have influenced exposure levels, including differences in frequency and intensity of gold-amalgam burning, which is the main route of Hg exposure (Harari et al. 2012).
Spin to stall was first introduced in Anglo American Coal in South Africa where it has been successfully used for over a decade, though implementation of South African spin to stall resin in Australia has proven to be near impossible due to a significant difference in geotechnical conditions, mining method, and, subsequently, roof bolting equipment.
Such differences are easily attributed to differences in data mining methodologies.
Differences in the mining criteria usually lead to significant deviations in the number of microsatellites identified in a given species using the same dataset [ 29].
She and the other teachers in the school should be commended for caring and making a difference in so many lives, including mine.
