Geological Complications and Environmental Hazards of the Cement Raw Materials Quarry Sites in Yemen

Extensive field and site investigations were conducted to assess evaluate the situation in presently exploited quarries of cement raw materials Yemen. These have several geological complications represented mainly by high elevations, steep slopes, rugged topography, heterogeneity bed thickness, lithologic composition quality, presence igneous sills dykes, intensive fracturing jointing abundance karstification features. Moreover, processes quarrying related operations negative environmental impacts most important which are soil failure, overburden land sliding, toppling rock falls (which result considerable mass wasting) emission dust noise. Generally, more hazardous gypsum basement rocks than those carbonates volcanics. Furthermore, problems conservation natural resources. primarily excavation valuable agricultural reclaimed lands improper exploitation fresh underground waters reserves decreased drastically. To deal with above-mentioned problems, a number recommendations outlined. They comprise mitigation measures must be strictly implemented. Also, it is almost importance conduct prospecting for new occurrences their possible substitutes as well additional groundwater
