Various Methods in Mining Industry

The nature of mining processes creates a potential negative impact on the environment both during the mining operations and for years after the mine is closed. This impact has led to most of the world's nations adopting regulations to moderate the negative effects of mining operations. Safety has long been a concern as well, though modern practices have improved safety in mines significantly.

Mining methods are constantly changing and improving as companies forge new technologies to enhance rates of extraction and minimise impacts such as noise, dust and land and water disturbance. There are numerous mining methods utilised around the world including open-cut mining (truck-and-shovel, strip mining, quarrying and dragline), underground mining (stoping methods, bord-and-pillar, longwall, caving methods, cut-and-fill and retreat benching) and highwall mining hammer crusher.

There is a wide variety of methods of extraction which one can choose from as the orebodies have shapes and sizes. The orientation and shape of an orebody, the strength of the ore and thesurrounding rock and the form in which the valuable materials are distributed are different for each ore area. These factors among others are what will influence the selection of a mining method and the overall plan for developing the orebody.

Operating mines vary in size from small underground operations (some of these operations have only a few levels of production and may produce less than 100 tonnes of ore per day) to the large open pits (some of which move thousands of tonnes or ore and waste rock per day). china magnetic separator:http://www.hx-crusher.com/magnetic_separator.html

Getting Down to the Bottom

The primary opening into an underground mine can either be a shaft, a ramp (which can also be called a decline) is driven downinto the earth, or an adit which is a horizontal opening that is driven into the side of a mountain or...
