Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Worker safety has long been a concern as well, and modern practices have significantly improved safety in mines.

DIRO-MORREH MINE

The overall economic goal in mining operation is to remove the slightest amount of material while acquiring the greatest return on investment by processing the most marketable as well as profitable mineral product. To minimize capital investment while accessing the highest valued material within a mineral deposit, a mine plan should develop that exactly details the manner in which the ore body would be extracted and processed. The decision to develop a mine mainly occurs after exploration has characterized the ore deposit and geological settings as well as feasibility studies have defined the options for mineral extraction. Information that is necessary to establish a mine development plan may include economical, geological, geographical and technological information. According to aforementioned information, Quarrying mining method was the chosen extraction method for Diro-Morreh mine. According to geological surveys, an intrusive magmatic dyke (basaltic dyke) came out from limestone beds and could make marble from limestone in late Pleistocene. Since this mine mainly contains 3 types of stones namely: limestone, Marble and Basalts. After physical and chemical analysis Basalt and Marble defined as target materials and mine plane based on their geological, geographical and market situation have been prepared. Regarding to geological condition two different extraction techniques for marble and Basalts deposits defined. According to these plans marble can be extracted by drill and blast technique can be and employing mechanical extraction machine is the most suitable option for extracting Basalts. Following pictures explain the each extraction techniques.
