6 FAQs about [The spontaneous combustion rock drill is difficult to start]

What is spontaneous combustion management?

Spontaneous Combustion Management Spontaneous combustion is a process that affects a broad range of mining operations, including gold, silver, copper, lead-zinc, nickel, tin, iron ore and coal (brown and black).

How should a mine respond to spontaneous combustion?

The mine should have in place response plans for the mitigation of the effects of spontaneous combustion, including means for the protection of personnel and the mine. The mine should determine indicators for the earliest detection of spontaneous combustion, including gaseous & physical indicators (such as smell, haze, etc).

Is spontaneous combustion a hazard?

Spontaneous combustion describes the process of self-heating of coal by oxidation. After exposure by mining, coal undergoes a continuous exothermic oxidation reaction when exposed to air. A hazard exists when, in confined areas, the rate of heat accumulation due to oxidation exceeds the rate of cooling by ventilation or environment (figure 1).

What is the nature of risk arising from spontaneous combustion?

The nature of risk arising from spontaneous combustion is that it may be continuously variable not only between mines but also within an individual colliery’s workings.

What is spontaneous combustion of coal?

2. Fundamentals of spontaneous combustion Spontaneous combustion describes the process of self-heating of coal by oxidation. After exposure by mining, coal undergoes a continuous exothermic oxidation reaction when exposed to air.

Do you need a risk assessment for spontaneous combustion?

It is a requirement of the Regulation that a risk assessment must be conducted to identify all aspects of risk to health and safety associated with spontaneous combustion. The risk assessment must be conducted by a person or group that is competent to conduct the assessment, having regard to the nature of the hazard.
