Mining

they might mine under building which will leave the buildings on top less balance onto the ground so they might cave in on them.

Also because the walls might be ancient so they might start to crack and break.

HOPE THIS HELPS! :)

A sledgehammer, four stakes, and a pan complete the equipment list. Unless you want to protect your claim, then you must 'up your ante'.

Lack of gold deposits that can be mined economically. Even if gold is present, but it will cost $2000 per ounce to mine- when gold is selling for $1000 an ounce, it does not get mined.

You can get hurt. It can be dangerous mining.

The deepest mine in Europe is located in a small city called Pyhäsalmi in Finland. The depth is 1,4 km.

The cycle of boom and bust.

There are plans by K & S to explore the possibility of revitalizing the Mine. This was compiled due to that shafts are existing and above ground structures are relatively cheap to rebuild as the sinking of the shafts are expensive as they are already there. If water was to be in the shafts, it can be hauled away by rail and sealing of seepage from water could commense. This is only in the preliminary stages.

Tanzanite is mined in Northern Tanzania, on a ridge near Mererani, some 40 km southeast of Arusha.

The price of a jaw crusher is based on the size of the machine or the stone size you need to crush.

There are numerous techniques to unload coal from wagons. The methods are determined at the design stage of the wagon. Historically the wooden wagons were simply tipped individually with their wheel sets attached as part of the wagon. The tipping could have been along the wagon or to the side using very promitive systems of derricks & ropes. Loading of barges was often achieved by simply tipping the wagons sideways at a height with the material falling into the barge from an elevated rail system. An alternative was to lift the wooden hopper of the wheel sets with a crane to then rotate in the air and discharge the contents - used for early ship loading of coal. It is of note that current versions are used of wagon side tipping for certain large terminals.

In more recent history there are "Tipplers" which rotate one or two wagons at a time around their coupler to dump them, after which the whole train is "indexed" along the track until the next set is aligned ready to be tippled. This is not a continuous process due to the indexing. Another current technique is to design the wagons for bottom dumping with doors on the wagons that can be opened at the destination to dump into a hopper below the rails. These doors may across the wagon or along the wagon. Opening techniques were historically manual opening, however for high volume operations these operations are automated.

Opportunity cost can be defined as the cost of any activity measured in terms of the value of the next best alternative foregone (that is not chosen). It is the sacrifice related to the second best choice available to someone, or group, who has picked among several choices. Opportunity Cost is a choice depends on what has to taken up. We can have an option of two or more options has Opportunity cost. Opportunity Cost is helpful when calculating the price and profit of choices.

Although opportunity costs are not generally considered by accountants-financial statements only include explicit costs, or actual outlays-they should be considered by managers. Most business owners do consider opportunity costs whenever they make a decision about which of two possible actions to take. Small businesses factor in opportunity costs when computing their operating expenses in order to provide a bid or estimate on the price of a job.

Mining in the Philippines has led to environmental degradation, deforestation, and displacement of indigenous communities. It has also caused water pollution, soil erosion, and loss of biodiversity. Additionally, there are concerns about child labor and the violation of human rights in mining operations in the country.

Data mining is a computer science which extract patterns in data sets. It can be used to predict which people are most likely to respond to a sales offer or what type of garment is preferred by a certain type of customer.

The term data mining is generally known as the process of analyzing data from many different perspectives in order to correctly organize the data. Sometimes data mining is also called knowledge dicovery.
