There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.
Mining Valuation Techniques - P/NAV, P/CF, EV/Resource
The main mining valuation methods in the industry include price to net asset value P/NAV, price to cash flow P/CF, total acquisition cost TAC & EV/Resources. The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mine plan produced in a technical report

CDC - Mining - History of the Mining Program - NIOSH
Techniques were developed that allowed mining companies to determine the gassiness of coalbeds. Armed with this new technology, USBM researchers conducted a number of geological studies that identified the gassiness of most major coal basins. This information was used by most coal mining companies as a planning tool for methane control systems.

Uranium Mining Overview - World Nuclear Association
Generally speaking, uranium mining is no different from other kinds of mining unless the ore is very high grade. In this case special mining techniques such as dust suppression, and in extreme cases remote handling techniques, are employed to limit worker radiation exposure and to ensure the safety of the environment and general public.
TENORM: Uranium Mining Residuals | Radiation Protection ...
The mining of uranium ore through underground and surface methods produces varying types and amounts of bulk waste material, including: The earliest known use of uranium as a pigment dates to the Roman era, and for many years, it was used as a colorant in glasses, glazes, and dyes. The modern ...
Profitable mining with the help of radiation technology
is mostly a result of the high cost of mining it. Gold is mined commercially at gram-per-tonne levels, and few analytical techniques have the sensitivity to accurately measure metals at these ultra-low levels. Gamma activation analysis uses high-powered X-rays to excite specific elements in the ore, activating any trace of gold in the sample.

Control of Radiation Hazards in Underground Uranium Mines.
The primary control technique used by the mining industry is dilution with fresh air. Because the uranium is deposited in porous sandstone in most U.S. mines, the control of this hazard with dilution requires excessive volumes of air.
Uranium mining - Canadian Nuclear Association
When ore is located more than 100 metres below the surface, underground mining methods are more economical than mining by open pit. The first step in underground mining is to access the ore. First, miners dig vertical shafts to the depth of the ore, then cut a number of tunnels around the deposit.
