Abstract Through this paper the project team aimed to demonstrate utility and feasibility of using flights photogrammetric methods in surface mining mountainous areas. Thus, first part paper, working principles, applied methodology, criteria for selecting necessary resources are presented, later results obtained from case study limestone quarry Bistrița, Vâlcea presented. At same time, environm...

Bermuda is an Eocene age volcanic island in the western North Atlantic, entirely capped by Pleistocene eolian limestone. The oldest and most highly karstified limestone a 2 km2 outcrop of Walsingham Formation containing island’s 150+ caves. Extensive networks submerged cave passageways, flooded saltwater, extend under island. In early 1980s, divers initially discovered exceptionally rich divers...

In quarries for building material, the primary transportation mode is by truck due to its high mobility that suitable actual terrain conditions of mine. The characteristic work in these mines large amount cargo transportation, steep slopes, small turning radius, and therefore always potential hazards risks workers at article presents a method evaluating points identify assess level occupational...

The paper deals with the development of a dimensional rock sawing machine to optimize production small-volume stone products in limestone quarries by re-thinking use and transport equipment. A low-volume mining transportation adapter be developed for both can reduce number machines used mine. After cutting around block stone, material moved help machine. Cutting tests were performed determine w...

In this paper, we have the percussive rotational drilling regime that is determined by combination of speed tool, axial force applied on rock optimal values these parameters d epend in particular type tool and physico mechanical properties rocks to be felled. The aim research improve operating regimes rilling machines under conditions Algerian limestone quarries (Hadjar soud quarry) obtain a be...

Abstract Wadi Mawathil area is characterized by the existence of carbonates, represented “Egyptian Alabaster” (calcite alabaster) and “Bucchino” (recrystallized limestone). One most important geological heritage in Egypt Egyptian Alabaster quarries. The considered main economic resource study recrystallized limestone occasionally can be quarried. Field revealed that covered Middle Eocene rocks ...

Nowadays, the dimension stone industry performs a crucial role in world economy. Accordingly, quarries’ importance grows due to their different applications various construction, building, and decorative industries. Some issues threaten this provide financial risk that should be taken into account make smallest possible for investment. The presence of discontinuities rock mass has key function ...

Lapis lazuli has been used for more than 7000 years for the manufacture of precious objects and jewels. The main quarries for this stone are still active in Afghanistan, but there are other quarries that could have been exploited since antiquity in the Pamir mountains (Tajikistan), in Pakistan and in Siberia. For this reason a provenance study of lapis lazuli could provide answers to some impor...
