] KIBRIA M G, QUAMRUZZAMAN C, WOOBAID U A S, GOLAM C. Effect of longwall mining on groundwater for underground coal extraction in Barapukuria, Bangladesh [J]. Journal of Mines, Metals and Fuels, 2012......
. There were several methods available in the literature for recovering precious metals from aqueous solutions such as ion exchange, membrane filtration, evaporation, solvent extraction, foam separation......
be extracted from the result of simulation, and the extraction steps are as follows: (1) As shown in Fig. 3, the stroke at the maximum tensile force is viewed as the fracture stroke; (2) The fracture......
, mainly because of the local extraction of ceramic particles. The worn surface exhibits irregular delamination wear, leading to a subsurface crack that grows progressively and eventually shears onto......
in the middle cross-sections during the freezing phase. This step allowed preserving the soil fabric well when producing fresh planes for SEM observations [21]. Figure 2 Extraction of small samples......

disasters due to the extraction of underground coal seams is a significant challenge in underground mining engineering [1-6]. This task is further compounded by the growing trend for coal......
to the prevalent heat extraction, while the dendrites in the partly remelted zone were larger since they were able to coarsen, when they were in the contact with the melt. Fig. 5 Light micrograph......
extraction and other fields, showing a wide range of industrial applications [1-3]. Besides, hydraulic fracturing can lead to the phenomenon of cracking, damage expansion, and even overall instability......
