Mining is a gather profession it is a good money making and a very easy profession to level and keep up with.If you are interesting in doing mining jaw crusher go to any major city ask a guard where the mining trainer is and train it up!When prospecting for Ore the mining ships head for the asteriod belts where you can set up base and crop for various sorts of ores that can be refined into materials to build ships and weapons. The problem is trying to get the Ore out safely to the refining stations, the raw ore itself is unusable so you want to refine it to make it sell-able and make a profit.
As GIS data is used more and more across an increasing array of industries, people are quickly learning about the huge differences it can make. GIS stands for geographic information systems, and it is a tool used to create new maps and update old ones. GIS data, sometimes referred to as ‘geospatial’ data, has the ability to interpret and analyze different forms of mapped data. It is often used for industries that spend the bulk of their time below the earth’s surface, such as with mining. When geospatial data is used in the mining industry, it typically creates a handful of important benefits for the mining company.
Whatever the substance is that’s being mined, GIS data can be used to help find deposits faster. Often, a great amount of resources is used to actually locate the minerals or other substances below the surface. Geospatial data makes use of the latest software to locate deposits without using up the same number of resources. That means a mining company can figure out where to dig without actually having to break the surface first and use up a bunch of time and man power.

How GIS Data is Displayed
Not only will GIS data help a mining company figure out where to dig, it can also provide details about what lies between the miners and their object. The company will save even more time knowing how much rock they must get through in order to establish a mine and get business rolling along. Eliminating a lot of the guesswork from the mining process is what makes the geospatial element so valuable. When time is saved, then man-hours are saved and ultimately money is saved, making for a more profitable mining experience. By not having to dig so much during the whole process, it also saves natural resources. screw classifier:http://www.crusher-machine.com/27.html

GIS data can be shared quickly and with the touch of a button, which enhances the overall decision-making process. When everyone involved can see exactly what is going on in real time, the people who make the decisions don’t have to be right at the site in order to do so. When members of management back in an office can exchange information with workers in the field, so much time is saved and decisions are made based on how the situation really is, rather than some outdated version or someone’s guess.
No one would dispute that the mining industry is a challenging one. Many innovations have been made to make the situation safer for miners, and the use of GIS data is certainly one of them. Although it isn’t a physical product or safety device, anytime you can get a good look underneath the surface, the safety of the workers is going to be enhanced. Knowing where to dig and seeing the structure below the surface will ultimately lead to fewer injuries and fewer casualties. Knowing where to dig is important for many reasons, but knowing where not to dig may even be more important.

Cement is the essential ingredient in concrete, which is the world's second most consumed substance after water. Portland cement is a local product made in Britain and even invented here. No school, house, road, hospital or bridge could be built without it.
Though “cement” and “concrete” are often used interchangeably, concrete is actually the final product made from cement. The primary component of cement is limestone. To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement.
Cement plant manufacturing is highly energy – and – emissions intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO2. Given its high emissions and critical importance to society, cement is an obvious place to look to reduce greenhouse gas emissions.
The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO2emissions.
The direct emissions of cement occur through a chemical process called calcination. Calcination occurs when limestone, which is made of calcium carbonate, is heated, breaking down into calcium oxide and CO2. This process accounts for ~50% of all emissions from cement production.
Indirect emissions are produced by burning fossil fuels to heat the kiln. Kilns are usually heated by coal, natural gas, or oil, and the combustion of these fuels produces additional CO2 emissions, just as they would in producing electricity. This represents around 40% of cement emissions. Finally, the electricity used to power additional plant machinery, and the final transportation of cement, represents another source of indirect emissions and account for 5-10% of the industry’s emissions. ball mill:http://www.crusher-machine.com/21.html
Alternatively, efficiency measures can reduce the demand for fuel by addressing the production process itself (such as switching from inefficient wet kilns to dry ones) or through technical and mechanical improvements (such as preventative maintenance to repair kiln leaks). While some estimate that energy efficiency improvements could achieve emission reductions of up to 40%, some industry analyses suggest that producers may have already exhausted this potential. Without additional financial incentives (such as subsidies or a tax on carbon), further breakthroughs could be difficult.
Reducing emissions from the calcination process means looking to a material other than limestone. Blended cement replaces some of the limestone-based clinker with other materials, primarily coal fly ash and blast furnace slag. Blended cement could reduce CO2 emissions by as much as 20%, but widespread use of blended cement is limited by other environmental regulations (these substitutes can contain toxic heavy metals); the limited availability of substitute material; and some building code restrictions (blended cement can take longer to set).
Finally, CO2 emissions can be captured after they are produced through carbon capture and storage (CCS).In addition to traditional CCS methods, which are already employed in some power plants, concrete producers can actually use their own product as a sink for CO2. Through the process of accelerated carbonation, CO2 penetrates concrete and reacts with calcium hydroxide in the presence of water to form calcium carbonate; the result is stable, long-term CO2 storage. As a mitigation technology, accelerated carbonation can be achieved by exposing freshly mixed concrete to flue gases with high CO2concentrations.
