Coal losses are very high in India due to mine firescaused by spontaneous combustion in more than 200 coal mines in India. High efficiency coal extraction should be given more importance and further coallosses due to spontaneous combustion should be controlled. In this paper, it is discussed how
Preventing Spontaneous Combustion in Stored Coal Hugh quantities of coal are stored in bunkers, silos, hoppers and open air stockpiles. How susceptible such stocks of coal are to fire from spontaneous combustion depends on a number of factors, from how new the coal is to how it is piled. Recommendations: o Know your coal.
Jan 01, 2013· Majority of fires existing today in different coalfields are mainly due to spontaneous combustion of coal. The auto oxidation of coal ultimately leads to spontaneous combustion which is the major root cause for the disastrous of coal mine in leading and coal producing countries like USA, China, Australia, India and Germany.
Oct 07, 2016· This heat increases the temperature of the coal. Hence addition of excessive moisture for suppressing the dust / fire shall be avoided. During the spontaneous combustion of coal, some gases would be produced. This gas is also carried by the wind and causes pollution in the surrounding environment. Spontaneous combustion in a Coal stockpile 6.
Sep 01, 1995· Spontaneous combustion occurs due to the self-heating characteristics of coal. Given the right mixture of oxygen, moisture, heat, time, pressure and physical size, coal begins to smolder.

Coal mine waste tip spontaneous combustion is a world-wide environmental concern. The practice for preventing as well as extinguishing the waste tip spontaneous combustion in China has been undertaken for 15 yr with the first practice at Fenxi Coal Mine Management Bureau. In this paper, the current development of coal mine waste tip spontaneous combustion management in China is …
India has the largest concentration of coal fires, and it is estimated that 80% of those fires started due to spontaneous combustion. Indian coal fires were first documented in coal fields located in Raniganj back in 1865. In addition, mines in Jharia, Jharkhand are famous for their rich coal resources, but records show nearly 70 fires have been burning for over 100 years dating back to 1916.
Spontaneous combustion that leads to coal fires in power plants can cause major destruction. Unless handled correctly, the results can be catastrophic in both damage to power plant assets and, in a worse case scenario, the loss of human life. Spontaneous combustion, or self-heating, is most common in
Preventing spontaneous combustion coal fires involves attention to many different factors. Among the most critical are the type, age, and composition of coal, how it is stored, and how it is used.
Spontaneous combustion (SPONCOM) of coal is well known to be a serious threat to the safety of mineworkers, mining equipment and to the environment. It is also the biggest reason behind the coal ...
Nov 27, 2015· Exposure of underground coal to atmospheric oxygen causes spontaneous combustion. And Indian coal, with its high ash content, ignites at a relatively low temperature, 122 degrees Fahrenheit.
Coal emitting methane: Methane is a highly flammable gas at concentrations of between 5% and 16% in the air. Such concentrations inside cargo spaces will create a flammable atmosphere and can lead to explosion if a source of ignition is introduced. It is therefore strictly prohibited to not carry out any hot work on deck, inside cargo holds or ...
Kingdom, South Africa, Poland, India, and some U.S. coal mines (Bessinger 2005 and Ray 2007). The pressure balancing system at the Austar coal mine is a good example of the application of this method in controlling spontaneous combustion fires. In this mine, spontaneous combustion was spotted in the gob of a mined out panel.
spontaneous combustion in coal-storage facilities. These include recommendations for the shape, height, and composition of stockpiles. The significance of spontaneous coal fires in stor-age facilities was conveyed in the testimony of John Dilley to the U.S. Senate (1912). Dilley, of South-ampton, England, was a survivor and fireman in the
combustion. Knowing the proneness of coal of the one can take preventive measures to avoid spontaneous combustion and protect live and property, safeguard environment and economic aspects of mining [1]. A number of methods have been adopted over the years to identify the proneness of coal to spontaneous combustion.
how to protect coal from spontaneous combustion in india. New film exposes "hell on earth" in India's eastern coal fields. Their only source of fuel is coal collected by hand from the slag heaps, as spontaneous combustion...
The Spontaneous Combustion of coal in the coal storage is serious issue now a days due to global warming and other exothermic processes in coal stockpiles such as microbial metabolism, oxidation at low temperature, absorption & desorption of water by virtue of differences between real and equilibrium moisture content in coal and air.
Mar 01, 2013· Any amount of PRB coal that will remain stagnant in the silo under funnel flow conditions will be prone to spontaneous combustion. Thus, for materials like PRB coal, mass flow is recommended due ...
