    Book review: Production, Safety and Teamwork in a Deep-level Mining Workplace In almost any industry, the day-to-day experiences of workers directly shape production processes.   Could this be an explanation for Spontaneous Human Combustion? What strikes me is: 1 - Physically speaking, we humans are bags of salty water. 2 - It is cause by a radio frequency energy field, something that is invisible and can be projected at a distance, therefore making the combustion look like it is spontaneous, with no apparent cause.

    Air Deficient, Coal Combustion Ex- periments The concept of two-stage combustion provides for a substoichiometric quantity of air (that is, less air than is required to burn the coal completely to COa and H2O) introduced into the first stage of the fluidized bed to which coal is fed. Formation of CaCOa and inhibition caused by chemical. Fuel, its combustion and economy: comprising an abridgment of A treatise on the combustion of coal and the prevention of smoke, with extensive additions on recent practice in the combustion and economy of fuel: coal, coke, wood, peat, petroleum, etc. / (London: [s.n.], ), by Charles Wye Williams and D.

In China, coal is still one of the principal energy resources and it is expected that more coal mining projects are needed in the future. As mining operations continue to increase their production rates and discover more ore reserves, mine safety issues have become more urgent.

Additional Physical Format: Online version: Smith, Alex C. Inhibition of spontaneous combustion of coal. [Washington, D.C.]: United States Dept. of the Interior. @article{osti_, title = {Spontaneous combustion studies of U.

coals}, author = {Smith, A.C. and Lazzara, C.P.}, abstractNote = {This report describes laboratory studies conducted by the Bureau of Mines on the spontaneous combustion of U.S.

coals. Approximately 11 pct of U.S. underground coal mine fires are attributed to spontaneous combustion. Fig. indicates the system flow of pulverized coal combustion power station.

In Japan, coal is imported and unloaded at the port and is kept in stockpile. In stockpile yards, the reentrainment of coal particle by the wind and spontaneous combustion of coal are important problems. As a monitoring technology of reentrainment of fine coal.

When Arrhenius equation is used to solve the kinetic parameters of the coal spontaneous combustion, the coal temperature should be processed in segment. Preparation and Inhibition Characteristic of Multi-Phase Foamed Gel for Preventing Spontaneous Combustion of Coal.

Underground coal mines are required to manage the risk of spontaneous combustion and the initial part of this process is to obtain an assessment of the spontaneous combustion propensity of the coal.

Downloadable (with restrictions). Abstract The existing coal self-heating inhibitors usually have the shortcomings of short effective time and low inhibition effect. This study proposed a kind of controlled-release inhibitor and analyzed their differences in inhibition effects compared with existing inhibitors on coal self-heating.

The controlled-release inhibitor is made from the synthesis of Cited by: Given the obvious drawbacks of the coal inhibition systems described above, an intelligent self-foaming hydrogel filled with EG from copolymerization of corn straw, 2-acrylamidemethylpropanesulfonic acid (AMPS), and acrylic acid (AA) was produced and applied to inhibit the spontaneous coal combustion.

The hydrogel exhibited good thermal Author: Liancong Wang, Benjamin Tawiah, Yongqian Shi, Suncheng Cai, Xiaohui Rao, Chuan Liu, Ye Yang, Fuqiang. Turunc, M. Raab and R.

Spontaneous combustion of coal is a major cause of coal mine fires. It not only poses a severe hazard to the safe extraction of coal resources, but also jeopardizes the safety of mine workers. The development of a scientific management system of coal spontaneous combustion is of vital importance to the safe production of coal by: 9.

In recent years, the ecology, security, and sustainable development of modern mines have become the theme of coal mine development worldwide.

However, spontaneous combustion of coal under conditions of oxygen supply and automatic exothermic heating during coal mining lead to coalfield fires. Coal spontaneous combustion (CSC) causes huge economic losses and casualties, with the Cited by: The propensity of coal to undergo self-heating and spontaneous combustion is a major problem wherever coal is being mined, stored, or transported; it poses problems for both coal producers and users.

Accordingly, it has been the subject of extensive fundamental and practical research for well over a. Based on the deep study of the mechanism of coal spontaneous combustion, this paper proposes new efficient inhibitors preventing coal spontaneous combustion from the perspective of inhibition of free-radical chain reactions.

Chifeng coal samples were used as the research object, and six different types of antioxidants were selected as the inhibitor for low-temperature oxidation by: Abstract: Based on the deep study of the mechanism of coal spontaneous combustion, this paper proposes new efficient inhibitors preventing coal spontaneous combustion from the perspective of inhibition of free-radical chain reactions.

Chifeng coal samples were used Cited by:   The occurrence of spontaneous combustion is not limited to coal but the phenomenon is known to take place in a number of coal-shale, pyritic black shale and coal refuse (Kim and Chaiken ; Onifade and Genc e, f, g; Restuccia et al.

; Rumball et al. ).The principles that control spontaneous combustion are similar in all cases, irrespective of the material that is by: 6. It is imperative to have an in-depth understanding of the effect of extraneous moisture on the spontaneous combustion of coal not only for the control and prevention of coal spontaneous combustion in the coal mining industry, but also for the optimization design and application of the technological process.

A Method For Evaluating The Spontaneous Combustion Of Coal. Coal spontaneous combustion has always been a worldwide problem which causes waste of coal resources greenhouse gas emissions and other atmospheric environmental pollution problems although coal temperature monitoring is the most direct and accurate means of predicting the spontaneous combustion of coal the coal temperature.

Inhibition of Spontaneous Combustion of Coal. INHIBITION OF SPONTANEOUS COMBUSTION OF COAL By Alex C. Smith,1 Yael Miron,2 and Charles P. Lazzara3 ABSTRACT This report describes laboratory studies conducted by the Bureau of Mines to evaluate the effectiveness of 10 additives to inhibit the self~heating of coal.

Assessing and managing spontaneous combustion of coal 4 Abstract This report summarises the most common, practical methods used to determine the propensity of coal to self-heat and considers the external factors which can combine to result in a spontaneous combustion event.In direct combustion, coal is burned (i.e., the carbon and hydrogen in the coal are oxidized into carbon dioxide and water) to convert the chemical energy of the coal into thermal energy after which the sensible heat in the products of combustion then can be converted into steam that can be external work or directly into shaft horsepower (e.g.
