Dust formed during drilling in natural stone quarries

Bulletin of Engineering Geology and the Environment - Dust mass concentration and concentration decrease was studied in two natural stone quarries in Finland. The dust mass concentrations produced...     

Mixed reality web service platform

This paper presents a RESTful Web service platform for applications for both Web browsers and mobile clients. Having a common service backend makes creating applications fast, simple, and open to third parties. The paper presents two mixed reality applications that have been built on the platform. It summarizes requirements for a mixed reality platform and defines a mixed reality domain model that the platform and applications share. In addition, it describes how the clients can use the REST interface to perform operations on user-generated content, as well as access real-life commercial geo-content such as street-view panoramas and building models.     

Post-mining solutions for natural stone quarries

After-use solutions for natural stone quarries were studied for planning possible ways of using an abandoned (some other word might be better) quarry area. Characteristics of a natural stone quarry include physically stable quarry faces and benches created by quarrying, a water pond at the bottom of the quarry, and piles of leftover stone material. These features can be utilized as central elements in the quarry after-use. Scuba diving, climbing, and forestry are traditional and affordable afteruse alternatives, while fish or crab farming, rock building, storing, and amusement parks are more challenging solutions. The quarry can also be used for culture, learning, and research purposes.     

A review of dust emission dispersions in rock aggregate and natural stone quarries

Fugitive dust constitutes one of the most severe environmental problems in quarries because it escapes capture. This review aims to provide overview of dust concentration caused by quarrying by synthesising the current knowledge. The 25 studies explored here were conducted in open-pit quarries or mines. Three main dust sources surfaced from the studies: drilling, crushing and hauling. Analysis revealed a range of dust concentrations caused by different quarrying operations. Crushing was the most significant dust source, while drilling caused the highest variation. Dust concentration decrease was observed with increasing distance, but the retention was incoherent due to local dust sources.
