Spontaneous combustion of coal (Technical Report) OSTI.GOV
The U.S. Bureau of Mines conducted a worldwide literature review of bleederless ventilation practices to evaluate their use as a spontaneous combustion control measure in U.S. coal mines. Factors that must be taken into account in the design and use of these systems include seal construction, the use of ventilation control devices, the use of methane-drainage systems in gassy mines, and the ground

Evaluation of the spontaneous combustion of coal (SCC)
latter conditions, coal oxidation is being initiated and the processes of self-heating are observed. The average rate of coal heating from 40 to 70 ºC is considered to be the index R70 (ºC/h). The higher the value of such an index, the more prone the coal is to spontaneously combust (see Table 1). Such a method is the most effi cient one with

2021-4-24 Spontaneous combustion occurs not just in coal but in other piles of materials including hay compost manure and pistachio shells. We have even seen a similar problem in sugar cane bagasse at the 2017 Cape Town MISG 1. There has been a wealth of literature in the past few decades explaining the spontaneous combustion of coal.

Abstract. To investigate the effect of coal metamorphism on the probability of coal spontaneous combustion (CSC), five types of coal sample were subjected to a temperature-programmed testing system. The gas indicators and limiting parameters of CSC were analysed and the characteristics of different ranks of coal were observed during low-temperature ...

Spontaneous combustion occurs in coal seams, stockpiles, and coal wastes when the rate of heat generation from the oxidation of organic matter exceeds the rate of heat dissipation . However, other factors could also favor or hinder spontaneous combustion [ 4 ].

Study on the Spontaneous Combustion Tendency of Coal
2021-3-5 1. Introduction. Spontaneous combustion, which generally exists in coal mines, is one of the five major mine natural disasters. Additionally, spontaneous combustion of coal has caused safety accidents, 1−5 economic losses, 6,7 and environment issues. 8−12 Hence, it is of great significance to assess the extent of the spontaneous combustion tendency for reducing spontaneous combustion of ...

2016-7-14 In China, spontaneous combustion of coal has caused numerous accidents, resulting in economic loss and human casualties. On June 23, 2014, the spontaneous combustion of coal triggered a gas explosion in a mining area that killed 22 people in Chongqing, China [].In the same year (November 26, 2014), 24 people perished in Liaoning Province []. ...

Spontaneous combustion studies of U.S. coals
2021-5-22 Approximately 11 pct of U.S. underground coal mine fires are attributed to spontaneous combustion. The relative self-heating tendencies of 24 coal samples were evaluated in an adiabatic heating oven. Minimum self-heating temperatures (sht's) in the oven ranged from 35 deg c for a lignite and high-volatile c bituminous coal, to 135 deg c for two ...

The coal is hosted within a Triassic sedimentary sequence, underlain by Pre-Cambrian basement and occurring within four distinct lobes (Parkin 1953). The coal within Lobe B was deposited in three series – termed Upper, Main and Lower Series (Figure 2). Risk profiling and control of spontaneous combustion for coal mine closure B Williams et al.

Effect of natural convection on spontaneous combustion of ...
Spontaneous combustion may occur in a coal stockpile when the heat generated within the pile cannot be dissipated at near ambient temperature. Under practical conditions, natural convection enhances the rate of heat removal from the bed and shifts the ignition to lower particle sizes (higher reactivities).

The object of this study is coals of different stages of metamorphism and the volatile products of their thermal decomposition. Currently, based on the basic genetic signs of metamorphism, there is no reliable regulatory framework for determining the hazardous properties of mine plastics, including the propensity of coal for spontaneous combustion.

Coal mining was widespread in the central belt of Scotland from 1830 until the 1970’s and created a legacy of waste tips or ‘bings’ that still dot the landscape. High content of coal fines and carbonaceous shales, make bings very prone to self-heating and smoldering combustion. A 30 m high waste heap at Bogside, North Lanarkshire, Scotland, started to smoulder in 2009, approximately 80 ...
