The pros and cons of coal energy show us that this technology has had a positive impact on society in the past, but our future may lie elsewhere. Although it is an affordable resource and provides reliable power, the potential damage to the planet may outweigh many of the benefits that can be obtained.

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

Underground coal mining produces finely divided coal dust that deposits throughout the mine and serves as a source of combustible material for coal dust explosions. Limestone powder, known as rock dust, is spread throughout the mine workings on a regular basis. This rock dust serves to inert the coal dust when applied in the proper proportion.

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before

In Environmental Impacts of Coal Mining & Utilization, 1987. 4.1 Basic Principles. Coal gasification means the complete conversion of coal into gas using heterogeneous gas solid reactions. The main process is the reaction of the carbon of coal with steam, at pressures below 10 MPa and temperatures above 750°C, to form a "synthesis gas" containing mainly CO and H 2 with smaller amounts of

13-1-2020· Carbon Dioxide Emission Factors by Coal Rank and State of Origin. The (arithmetic) average emission factors obtained from the individual samples (assuming complete combustion) (Table FE4) (10) confirm the long-recognized finding that anthracite emits the largest amount of carbon dioxide per million Btu, followed by lignite, subbituminous coal, and bituminous coal.
