Claire Symes reports on one award winning project. Public opposition to the opening or extending of a new quarry often focuses on the loss of countryside, but through careful management quarries can enhance the natural landscape. Growing numbers of quarries are being successfully restored and managed to create habitats for wild animals and plants and to offer facilities for local communities. Cemex's Attenborough Quarry near Nottingham, UK is a shining example of quarrying, nature and the local community working in harmony. The quarry itself is nothing out of the ordinary - http://www.aggbusiness.com/rss-comments.asp?id=9 Mon, 23 04 2007 10:05:05 GMT http://www.aggbusiness.com/article.asp?id=29 CE markings of asphalt materials will bring traceability that could clear the way for easier high performance recycling.

Patrick Smith reports One of the major reasons for the regulations is that people living or working near, or even in quarries, could be affected by flying rock, the shock waves from a blast or the noise. Dust could also be problem, and concerns have been expressed about the possible effects on wildlife and the natural environment. http://www.aggbusiness.com/rss-comments.asp?id=227 Tue, 09 10 2007 00:05:05 GMT http://www.aggbusiness.com/article.asp?id=228 The reasons for encouraging the use of heavy hammers to replace explosives in quarries are mainly those of environmental regulations, but also of cost reduction. The process of rock breaking with mobile hydraulic hammers, more traditionally used for secondary breaking of large blocks, is becoming increasingly popular, and according to some experts can increase productivity because o http://www.aggbusiness.com/rss-comments.asp?id=228 Tue, 09 10 2007 00:05:05 GMT http://www.aggbusiness.com/article.asp?id=229 Caterpillar says its rippers can be used to rip rock with a high degree of stratification; frequent planes of weaknesses (fractures, faults and laminations); weathering, such as moisture permeated formations; brittleness; low compressive and tensile strength, and low field seismic velocity. These are the first factors to evaluate in deciding whether ripping is, or is not, possible in a quarry.

Noise, dust and vibration are all issues that can cause friction between quarry operations and the surrounding local communities and are all problems the quarrying industry is working to mitigate. Sources of noise and vibration can be fairly easily identified and isolated but preventing dust is more of a challenge as there can be multiple sources and deposition rates can be very weather dependent.
