The second stage of the coal fuel cycle is the mining and subsequent processing of coal from underground and surface mines, described in Chapter 4. Coal processing can include a variety of steps—crushing, screening, and wet or dry separations—to reduce the mineral matter (ash) content of coal prior to transport and use.
INTRODUCTION. The intended purpose of this Website . is to provide a reference document for all aspects of underground coal mining in Australia (though there may be references to overseas practices where these could be of interest).
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining .

Introduction. Coal mining in Poland is confined to three coal basins: the Upper Silesian Basin (USB) where coal exploitation has lasted for 250 years, the Lower Silesian Basin (LSB) around Nowa Ruda and Wałbrzych, and the Lublin Basin (LB). Poland is the biggest producer of hard coal in the European Union.

Introduction and Overview This chapter summarizes OTA''S review of the mining technologies currently in use on Federal leases and the potential for commercial mining technologies to extract Federal coal reserves from deep underground seams. The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open
In active mining regions, bituminous coal is the most abundant coal. It has a a moisture content of less than 20 percent and a heat content range between 21 to 30 million Btu per ton in a moist, mineralmatterfree basis. Of the four ranks, bituminous coal accounts for over half (51 percent) of the demonstrated reserve base.
Coal Mining and Processing. Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the ground''s surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our ...
Coal takes millions of years to form. Coal is a combustible black or brownishblack sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
