Underground mining hard rock and Underground mining soft rock Mantrip used for transporting miners within an underground mine Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits. Ore, for processing, and waste rock, for disposal, are brought to the surface through the tunnels and shafts. Sub-surface mining can be classified by the type of access shafts used, the extraction method or the technique used to reach the mineral deposit. Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques. Other methods include shrinkage stope mining , which is mining upward, creating a sloping underground room, long wall mining , which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to support the roof of the room. Room and pillar mining often leads to retreat mining , in which supporting pillars are removed as miners retreat, allowing the room to cave in, thereby loosening more ore.

Instead, we need a civic solution, because democracy is at risk.

Collections of databases that work together are called data warehouses. This makes it possible to integrate data from multiple databases. Data mining is used to help individuals and organizations make better decisions. Data Warehouses A database consists of one or more files that need to be stored on a computer.
In large organizations, databases are typically not stored on the individual computers of employees but in a central system. This central system typically consists of one or more computer servers. A server is a computer system that provides a service over a network. The server is often located in a room with controlled access, so only authorized personnel can get physical access to the server. In a typical setting, the database files reside on the server, but they can be accessed from many different computers in the organization.
As the number and complexity of databases grows, we start referring to them together as a data warehouse. A data warehouse is a collection of databases that work together.

Nov 6, , The trigger for this tirade of being protectionist stems from a spate of proposals and potential laws on data localisation declared by Indian authorities recently. It is not just India that alone is an outlier in this gambit as such localisation policies have been in vogue in developed and developing countries since the inception of the Internet. To boot there are genuinely solid and valid reasons for impeding the free flow of data, the principal one being obsessive concerns and dread over privacy.
Even as some of the fiercest restrictions on data movements are in paranoid-about-personal liberty and freedom States such as Russia and China, 22 out of the 27 nations of the European Union EU too follow data localisation measures.
Data mining is the process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.
There are, however, other predictors that have many more distinct values and can create a much more complex histogram. Consider, for instance, the histogram of ages of the customers in the population. In this case the histogram can be more complex but can also be enlightening. Consider if you found that the histogram of your customer data looked as it does in figure 1. This summary can quickly show important information about the database such as that blue eyes are the most frequent.
By looking at this second histogram the viewer is in many ways looking at all of the data in the database for a particular predictor or data column. By looking at this histogram it is also possible to build an intuition about other important factors. Such as the average age of the population, the maximum and minimum age. All of which are important.

By , rapid economic growth has enabled India to catch up with China and the U. These three countries — the “G3” — now have by far the largest share of world GDP. By comparison, China’s average age is 46 and its working population has been declining. India has also managed to avoid many of the disruptive challenges experienced by China, since its market-based economy is already part of a liberal democracy, unlike the planned economy of its rival. India’s currency, the rupee, is now challenging the renminbi as the world’s strongest.

Here are six sobering facts about online dating services and a few suggestions for routing around the privacy pitfalls. The most pressing concern is that information about you may be exposed to future legal requests that might involve a criminal investigation, a divorce case, or even a legal tussle with an insurance company.

An alternative view of the best new ideas in science. The idea is that somebody proposes a project, such as creating a smartwatch, an art installation or a video game, and then asks the Internet crowd for money. But while many projects succeed, far more fail. The reasons for failure are varied and many but one of the most commonly cited is the inability to match a project with suitable investors. That raises an interesting question.
What kind of projects attract the most reliable investment? And how do investors find projects that match their own goals? Today, Jisun An at the University of Cambridge and a couple of pals say they have mined the data associated with a large number of crowdfunding projects to find answers to both of these questions.
