The present work intends to explore the impact of stone mine and crushing on environmental components in the Middle catchment of Dwarka river basin of Eastern India. Stone dust produced from the crusher units (∼10–11 tons/day) is not only injurious for human health but also other valuable components of the environment like air, water, soil ...

basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact. It is more usual, however, for them to exhibit porphyritic structure, with larger crystals (phenocrysts) of olivine, augite ...

Abstract. Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners.

1. Introduction. Commercial drilling through basaltic formations has been undertaken for over a century, (Luzier and Burt, 1974, Burns et al., 2012).Drilling through basalt is already common in many areas of the world to access water aquifers (Buckley and Oliver, 1990, Tolan et al., 2009), geothermal energy (Fridleifsson and Elders, 2005) and …

This wide range reflects differences in the mining and screening (sieving) processes (Table 1) that each quarry site uses to produce the basalt used in our study. The p 80 values for the Oregon basalt and Blue Ridge metabasalt were smallest because they were passed through finer sieves during production (1.18 and 1.34 mm respectively) …

Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. [1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath.
