Causes and prevention of fires and explosions in bituminous coal mines / By b. Edward Steidle and United States. es bibliographical references (p. 75).Mode of access: Internet Topics: Coal mines and mining, Mine fires. bituminous coal: a relatively soft coal containing tarlike substances called bitumen; known for releasing dangerous mixtures of gases that can cause underground explosions bleeder system: a system of ventilation entries surrounding the caved area of a.

Explosions in underground mines and surface processing facilities are caused by accumulations of flammable gas and/or combustible dust mixed with air in the presence of an ignition source.

While much progress has been made in preventing explosion disasters in coal mines, explosions still occur, sometimes producing multiple fatalities. in the event of a fire or explosion. While fire and explosion risk assessments have to be carried out both below ground and on the surface, this guidance relates primarily to fire and explosion risks below ground.

However, the general principles should be applied to those buildings and equipment on the surface of a mine where a fire or. PRB coal and bituminous coal, and a fire existed in one of the coal bunkers. Dust within the atmosphere of the tripper room was ignited by a minor explosion, or puff, within the bunker, which triggered a massive explosion in the tripper room, blowing out.

Scope. * This standard shall cover minimum requirements for reducing loss of Causes and prevention of fires and explosions in bituminous coal mines book and property from fire and explosion in the following: (1) Underground bituminous coal mines (2) Coal preparation plants designed to prepare coal for shipment (3) Surface building and facilities associated with coal mining and preparation (4) Surface coal and lignite mines A In the.

Causes of Mine Fires and preventive measures: Various causes of Mine Fires are 1. Spontaneous combustion 2. Electricity 3. Friction 4. Blasting 5. Explosions 6. Miscellaneous 1) Spontaneous Combustion: This is the self-heating of the coal or other carbonaceous material resulting eventually in its ignition without the application of external Size: KB.

The most common dust explosion occurs in underground coal mines. In coal mine tunnel, coal dust explosion is usuallycaused by gas explosion. Moving at the speed of sound, the pressure wave resulting from the gas explosion lifts the deposited coal dust in the air.

Then the gas flame reaches the coal dust causing a dust ex. Firedamp is flammable gas found in coal mines. It is the name given to a number of flammable gases, especially methane.

It is particularly found in areas where the coal is bituminous. The gas accumulates in pockets in the coal and adjacent strata, and when they are penetrated, the release can trigger explosions.

Historically, if such a pocket was highly pressurized, it was termed a. Report issued by the U.S. Bureau of Mines discussing coal mine fires and explosions during the fiscal year of Causes of the fires and explosions are presented, as well as the number of fatalities from each.

This report includes tables, and : D. Harrington, W. Fene. Causes and prevention of fires and explosions in bituminous coal mines / (Washington, D.C.: Dept.

of the Interior, Bureau of Mines, []), by Edward Steidle and United States. Bureau of Mines (page images at HathiTrust). This code of practice on the prevention of accidents due to fires underground in coal mines comprises two parts. Part 1 contains provisions applicable to all coal mines, namely a series of general operation precautions, together with provisions on the organization of the prevention and detection of fires and of fire fighting.

Part 2 contains additional provisions applicable to mines. Standard for Fire Prevention and Control in Underground Bituminous Coal Mines NFPA was withdrawn in Annual and incorporated into.

Statistics for show that mine transportation accidents accounted for 19 percent of fatalities in bituminous coal mines, second only to roof deficiencies as a cause of death.

Productivity per manshift increased from Tons in to Tons inbut the fatalities per million man-hours of exposure also increased from to 0. Unloading mining can effectively reduce geo-stress around coal seams and increase coal permeability, which results in the improvement of coal mine methane drainage and ensures the coal mining safety.

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 In addition, mines in Jharia, Jharkhand are famous for their rich coal resources, but records show nearly 70 fires have been burning for over years dating.

NFPA Standard for Fire Prevention and Control in Coal Mines provides critical safety requirements for fire and explosion protection in underground bituminous coal mines, coal preparation plants that prepare coal for shipment, surface buildings and facilities associated with coal mining and preparation, and surface coal and lignite mines Format: Paperback.

Coal mine fire is devouring coal seams in major coal-producing countries including China, the United States, India, and Indonesia. Many seams have been burning for decades and some for centuries. Coal fires are a natural phenomenon; however, coal mining by humans has assisted the propagation of these fires and thereby enhancing the.

The National Institute for Occupational Safety and Health (NIOSH) maintains list chronological listing of major mining incidents for the United States. Chart lists date, mine name, city, state, number killed, mining sector (coal, limestone, etc.) and type of accident (explosion, fire, etc.).

NIOSH also has data and charts related to mining Author: Linda Musser. Causes of Spontaneous Coal Fires The following general factors have been mentioned as contributing causes: 1. Coal handling procedures allowed for long-time retention of coal, which increases the possibility of heating.

New coal added on top of old coal created segregation of particle sizes, which is a major cause of heating. Size: 39KB. NFPA Standard for Fire Prevention and Control in Coal Mines provides requirements to safeguard lives and property from fire and explosion in underground bituminous coal mines, coal preparation plants that prepare coal for shipment, surface buildings and facilities associated with coal mining and preparation, and surface coal and lignite mines.

This standard shall cover minimum requirements for reducing loss of life and property from fire and explosion in the following: (1) Underground bituminous coal mines (2) Coal preparation plants designed to prepare coal for shipment (3) Surface building and facilities associated with coal mining and preparation (4) Surface coal and lignite mines.

A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure cases when fuel plays the role of a combustible material, the explosion.

Anthracite coal, bituminous coal, and lignite coal dust samples are tested with mean particle diameters of 50, 55, and 78 µm, respectively. Relatively low gas concentrations are tested in the range of % by volume. CDE are a major disaster accident in coal mines, often causing heavy casualties and huge economic losses [3,4].

In China, over 85% of underground coal mines face the risk of coal dust explosion. An old book from our office showed how to hand fire a low vol coal, just pile it in a cone and it will catch and burn, hi vol you fire on one side and then on the other side next firing, if you put it in a cone the gasses being driven off will smother the fire and can cause an explosion.
