In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task

During the past 15 years, a wide range of symptoms and complaints in patients thought to be related to extreme sensitivity to low levels of diverse and often nonquantifiable chemical exposures have been reported. This syndrome has been referred to as multiple chemical sensitivity or MCS (Cullen 1987). MCS has been characterized as the heightened, extraordinary, or unusual response of individuals to known or unknown exposures whose symptoms do not completely resolve post-exposure or whose sensitivities seem to spread to other chemicals (Ashford 1999). The syndrome is thought by Ashford to be a two-step process with an initial acute exposure to high concentrations of a substance and the subsequent triggering of symptoms at extraordinarily low levels of exposure to the same substance or different substances. He believes that repeated or continuous lower level exposures may also lead to the same type of sensitization. Ashford and Miller (1998) also postulate that this sensitivity may be the consequence of a variety of disease processes resulting from toxicant-induced loss of tolerancedescribed as a new theory of disease providing a phenomenologic description of those disease processes

This study investigates the values of pH, total dissolved solids (TDS), elevation, oxidative reduction potential (ORP), temperature, and depth, while the concentrations of Br, and potentially harmful metals (PHMs) such as Cr, Ni, Cd, Mn, Cu, Pb, Co, Zn, and Fe in the groundwater samples. Moreover, geographic information system (GIS), XLSTAT, and IBM SPSS Statistics 20 software were used for spatial distribution modeling, principal component analysis (PCA), cluster analysis (CA), and Quantile-Quantile (Q-Q) plotting to determine groundwater pollution sources, similarity index, and normal distribution reference line for the selected parameters. The mean values of pH, TDS, elevation, ORP, temperature, depth, and Br were 7.2, 322mg/L, 364m, 188mV, 29.6C, 70m, 0.20mg/L, and PHMs like Cr, Ni, Cd, Mn, Cu, Pb, Co, Zn, and Fe were 0.38, 0.26, 0.08, 0.27, 0.36, 0.22, 0.04, 0.43 and 0.86mg/L, respectively. PHMs including Cr (89%), Cd (43%), Mn (23%), Pb (79%), Co (20%), and Fe (91%) exceeded the guideline values set by the world health organization (WHO). The significant R2 values of PCA for selected parameters were also determined (0.62, 0.67, 0.78, 0.73, 0.60, 0.87, 0.50, 0.69, 0.70, 0.74, 0.50, 0.70, 0.67, 0.79, 0.59, and 0.55, respectively). PCA revealed three geochemical processes such as geogenic, anthropogenic, and reducing conditions. The mineral phases of Cd(OH)2, Fe(OH)3, FeOOH, Mn3O4, Fe2O3, MnOOH, Pb(OH)2, Mn(OH)2, MnO2, and Zn(OH)2 (3.7, 3.75, 9.7, 5.8, 8.9, 3.6, 2.2, 4.6, 7.7, 0.9, and 0.003, respectively) showed super-saturation and under-saturation conditions. Health risk assessment (HRA) values for PHMs were also calculated and the values of hazard quotient (HQ), and hazard indices (HI) for the entire study area were increased in the following order: Cd>Ni>Cu>Pb>Mn>Zn>Cr. Relatively higher HQ and HI values of Ni, Cd, Pb, and Cu were greater than one showing unsuitability of groundwater for domestic, agriculture, and drinking purposes. The long-term ingestion of groundwater could also cause severe health concerns such as kidney, brain dysfunction, liver, stomach problems, and even cancer

The manner in which rock is blasted in mining operations subjects the rock mass to stress resulting in breakage. Different blasting methods result in different stress distributions in the rock and may have a significant effect on subsequent comminution operations (Chi et al., 1996). The effects of blasting on crushing and grinding are poorly understood. Comminution may take advantage of internal cracking and weakness in the rock caused by an explosive shock from blasting. However, quantifying this phenomenon will require a multidisciplinary investigation involving the physics of rock breakage, mining and mineral processing, and the optimization of energy requirements between blasting and crushing for size reduction
