Abstract :
Nowadays various methods such as wire saw, chain saw and water jet can be used to extract dimensional stones.These methods have some advantages and disadvantages in respect to different criterion such as technical,economical, geological, and environmental and etc. Therefore, choosing a suitable method in stone mineextraction to achieve more efficiency considering technical and environmental aspects is necessary. In this paperfor selection suitable extraction method for travertine mines in Mahallat, analytical Hierarchy Process (AHP) andExpert Choice software is used. For this purpose, eight criteria including geological aspect, environmentalaspect, extraction time, cost, safety, cutting quality, application facility and performance method and threeextraction alternative including wire saw, chain saw and water jet have been taken into account. Regarding toresults of AHP analyze the chainsaw method with priority of 0.471 is the best mining extraction method forquarry mines in Mahallat. The results show that replacement of chainsaw method instead of usual method (wiresaw) caused to improvement of technical, economical, geological and environmental conditions of travertinemines of Mahallat.
