The elements of sustainable transport are about more than just the amount of fuel used. Whether it’s about a state or country-wide transport company or a smaller business that delivers freight around the town or city, sustainability is important because it not only helps to save the earth’s resources, but saves on costs for the company, something that should always be of importance.
Even though one train can take a great deal more freight than one truck, it is not nearly as efficient or as fast. Road rather than rail transport is much preferred these days, because trucks can deliver right to their destination without the need for that extra offloading and reloading onto trucks at both ends of the rail journey which requires even more labour and fuel resources.
What to Plant around Your Pool
Garden pools are increasingly becoming a favorite component of residential landscapes. Even homes that do not boast of a large land area are opting for garden designs that allow them to fit in cozy little pool. In order to refrain from messing up with the aesthetics of the shrubbery, it is important to choose the right plants to ornament the edges of your pool.
Before going into the details of what plants to choose, it is necessary to understand which ones to avoid. This considerably narrows down the scope of plants available to decorate your pool, and makes the whole process of decision making easier.
Why we mine for gold?
Since ancient Egyptian times, when gold was considered a divine metal and thought to be the flesh of the gods, the allure and magnetism of gold has translated through the ages. From the earliest days of royal and noble burials, it was the metal with which the Kings of Egypt surrounded themselves; it was the metal they placed within their tombs for use in the afterlife, it was imperishable, eternal and indestructible.
In 2008, GFMS Ltd estimated that the total gold supply was approximately 3,750 t. As gold is some 19.3 times heavier than water, this amount of gold would fill a box some 6 m wide by 6 m high by 6 m long.
Of the total gold supply in 2008, some 65% was from new mine production with the remainder sourced from recycling of gold ‘scrap’ and sales from central bank holdings.
Gold demand in 2008 was dominated by consumption in jewellery and fabrication (75%), with the remainder predominantly being investment demand.
Bendigo Mining’s Swan decline (underground tunnel) now stretches for a distance of some 6.5 km to a depth of about 850 metres beneath the City of Bendigo, tunnelling deep beneath the historic workings to access new untouched orebodies on the Deborah and Sheepshead lines of reef.
From the decline, diamond drilling is carried out at typically 120 m intervals to establish the location and dimensions of the ore bodies. Geologists log and cut the diamond drill core samples and send them away for assay to determine the grade of gold on each section of the reef.
With the grade and shape of the reef established, mining engineers are then able to plan the ore shapes that will be mined (the stopes) and determine how the orebody will be accessed and mined. Extracting and removing the ore is achieved by drilling holes in the rock face, packing them with explosives (charging the face) and then blasting the rock.
