Abstract.
The impacts of quarrying of the gypsum deposits on the environment at Maqna, Tabuk, were evaluated by intensive field studies including in situ testing, mapping and sampling of gypsum and well water. Field and laboratory tests were made to determine the engineering properties including tensile and compressive strengths, unit weight, fracture spacing and the rock quality designation (RQD) values. Results were used to determine the most suitable method for quarrying and extraction. Chemical analyses of gypsum and water well samples were conducted along with mineralogical analysis using X-ray diffraction analysis (XRD). Results show that there are no harmful impacts on the environment of the studied area associated with the extraction and quarrying of the gypsum deposits at the Maqna area. They also revealed that the gypsum can be quarried using a ripping technique, which does not create noise and/or vibration in the surrounding areas.
