“…They used four samples from three different mines located in Canada, which were mixed with four types of binders and six different types of mixing water chemical characteristics. It was found that the mixing water is an important parameter that affects the quality of the paste backfill mass and that, in contrast to the Portland cement based binder, slag-based binder hydration seems to be inhibited by the presence of soluble sulphates [13]. The results of this study clearly demonstrated the inefficiency of choosing paste backfill mixtures without testing first the tailings and mixing water characteristics.…”

“…Pastes prepared with brines and fly ash A significantly exceeded a minimum UCS of 200 kPa suggested by Potvin et al (2005) for mine backfill. Mahlaba (2007) showed that the pH of paste remained high even when acidic brines were used due to high alkalinity of fly ash which agrees with its use of neutralising acid mine drainage Gitari et al, 2006;Shang and Wang, 2005;Benzaazoua et al, 2002;Fester et al, 2008). The distinction exhibited by two fly ashes was attributed to the mineralogical differences especially lime deficiency and lower content of the amorphous phase in fly ash B (Ward and French, 2006;Donahoe, 2004).…”

a b s t r a c tTo meet the escalating demand of energy more coal ash and brines are inevitably produced as byproducts. Large volumes of these wastes and increasing environmental awareness necessitate the development of more sustainable methods to mitigate the environmental footprint. Paste backfill is one of the potential solutions to keep the energy industry sustainable. The behaviour of pastes was investigated by strategically varying brine composition mixed with the two types of fly ash. The results showed that fly ash plays a more prominent role in the behaviour of pastes than brines. It is therefore imperative to consider both fly ash and brine characteristics i.e. constituents of paste for the development of an environmentally sound paste backfill practice. Technically there are numerous benefits in pursuing the proposed solution.

“…The socalled high water refers to water volume content accounted for more than 95% of the total volume, and the 95% water volume is called common material [15][16][17] . Material consists of main material (A material, B material), subsidiary material (AA material, BB material).…”

Abstract-This paper introduced the advantages about the application of high water material in the filling mining under the combination of its actual situation of coal mine. These advantages included the fluidity, expansibility, strength of backfilling, initial investment of high water material and so on. The research results showed that high water material could control the surface subsidence effectively and liberate the coal resources under water, railway and building in a great extent. The success application of the high water material has certain social benefits and economic benefits, and even embodied the concept of "Green mining", meanwhile in response to strong call of harmonious mining ecological. The governers worked in the mine at all levels should spare no efforts to afflicate the application of high water material in the filling ming technology. As the coal resource decrease obviously, we should take some measures and methods to increase the rate of recovery.
