Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid. Throughout geological history, the development of deserts has occurred naturally; however, when deserts emerge due to unchecked depletion of nutrients in soil that are essential for it to remain arable, then a virtual "soil death" can be spoken of, [5] which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem with far-reaching socio-economic and political consequences. As recently as , considerable controversy existed over the proper definition of the term "desertification. However, this original understanding that desertification involved the physical expansion of deserts has been rejected as the concept has evolved. There exists also controversy around the sub-grouping of types of desertification, including, for example, the validity and usefulness of such terms as "man-made desert" and "non-pattern desert". The world's most noted deserts have been formed by natural processes interacting over long intervals of time.

Room and pillar variant of breast stoping , is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden. Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of active research. Room and pillar mining can be advantageous because it reduces the risk of surface subsidence compared to other underground mining techniques. However, because significant portions of ore may have to be left behind, recovery and profits can be low. The room and pillar system is used in mining coal , gypsum , [4] iron , [5] and uranium [6] ores, particularly when found as manto or blanket deposits, stone and aggregates , talc , soda ash and potash. Planning for the development of room and pillar mines operates in much the same way as other mining methods, [9] and begins with establishing ownership of the mine.

Mohammed Hefni, Maaz A. The effectiveness of mine backfilling depends on the properties of its constituents. The high cost of cement, which is commonly used as a binder in mine backfill, has led researchers to seek alternatives to partially replace it with other binders. This study investigated the potential to use nano-calcium carbonate NCC and natural pozzolans zeolite and pumice along with Portland cement PC in mine backfill. Two types of experimental samples were prepared: 1 gold tailings and silica sand to investigate the effect of NCC and 2 nickel tailings to investigate the effect of natural pozzolans.
