RECLAMATION AND ENVIRONMENTAL MANAGEMENT IN DIMENSION STONE MINING I. Ashmole1, M. Motloung2 1Greenstone Marble and Granite (Pty) Ltd 2Finstone (SA) (Pty) Ltd ABSTRACT From the point of view of the environmental impact created, dimension stone mining is a relatively benign industry.
INTRODUCTION TO MINING employed crude methods of ground control,ventilation,haulage,hoisting, had a greater impact than any other discovery until dynamite was invented by Alfred Nobel in 1867. Mining technology,like that of all industry,languished during the Dark Ages. Notably,a political development in 1185 improved the standing of
Health Hazards of Mining and Quarrying its proximity to the source of hazards and the effectiveness of hazard control methods. Sandstone can be up to 100% silica, granite up to 40%, slate, 30%, with lesser proportions in other minerals. Exposure can occur in any mining operation, surface or underground, where silica is found in the
impacts of large-scale mining projects involving these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum (bauxite), phosphate, and uranium. The Guidebook also does not discuss mining involving extraction of coal or aggregates, such as
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have

Environmental and social impacts of stone quarrying-a case study of Kolhapur District the biggest share of the benefits from quarrying; while local to know the local people perception about the impacts of communities suffer from the negative impacts
Aggregate mining is an extractive use of resources: mining alters the landscape and its natural hydrologic system. When a new pit or quarry is proposed or when an existing operation needs to expand, local governments and citizens typically have many questions about the impacts mining might have.

Mining Techniques for Sand & Gravel Other Sand Mining Methods. mining should be limited to locations where there is minimum impact upon the environment. A stream or river is a dynamic environment due to variation in the flow of water. Gravel bars will be present in many streams and rivers. Mining is preferable on gravel bars where there
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of
Two other methods of sawing find limited use in granite processing. One method, formerly widely used, involves the use of multiple strips of hardened steel, in a regular back and forth sawing action, in former years using sand, but today using carborundum, as the cutting agent.
Room-and-pillar mining A method of mining flat-lying ore deposits in which the mined-out area, or rooms, are separated by pillars of approximately the same size. Rotary drill A machine that drills holes by rotating a rigid, tubular string of drill rods to which is attached a bit. Commonly used for drilling large-diameter blastholes in open
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is
