slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...

Like most limestone mines, which produce the raw materials required for cement companies, the transportation cost of the raw materials used in the Shahrood Cement Company is high. It has been tried to build the crushing and grinding plant close to the mine as much as possible. On the other hand, blasting has harmful effects, and the impacts of blast-induced damages on the sensitive machinery, e...

This paper presents the geotechnical study and stability assessment of a Mining Waste Rock Dump (WRD) from Limestone Mine in city Dom Feliciano/Rio Grande do Sul (RS), south Brazil. A literature review is used to provide considerations on properties materials geometries adopted. These parameters were basis for evaluation performed realistic profiles WRD proposed expansion. The conclusions regar...

In this study, we developed a system to collect and analyze log data related truck travel times in underground mines using Bluetooth beacons tablet computers. When signal from installed at major mine is received by truck-mounted computer, the beacon information collected uploaded cloud server. A processing program integrates files into single file, calculating statistical values for each sectio...

Because grains comprise the major portion of diets for finishing beef cattle, and grains contain little calcium, limestone is typically added to finishing diets at levels of .7 to more than 1% of the dry matter. Feedgrade limestone varies in quality and consistency, which could alter performance responses by finishing beef steers. Selection of superior sources of limestone and(or) treatment of ...
