Mine Fires - an overview ScienceDirect Topics

Frictional ignition frequency in US coal mines is on the decline, but it still is a cause of concern because it has a potential to cause a mine explosion leading to a large-scale mine fire. Prevention of frictional ignition is based on the following: 1. Coal seam degasification to reduce original gas content of the coal seam by 50–80%. Horizontal boreholes drilled for degasification can also be used for water infusions.

The risk of fire on mining businesses - Australian Mining

30/03/2020  Wherever you have heat generation combined with potential mechanical or electrical component failure, the probability of fire is real. Consequently, consideration must be given to the costs of asset replacement and lost production. These costs are however, insignificant compared to the possible loss of life.

Fire safety of mining machinery – Improvement proposals ...

VTT in Finland has been studying fire safety of mining machines used in hard rock mines. The main causes of fires are short circuit of an electric cable, leakage of oil in hydraulic system, overheating of brakes and insufficient maintenance of the machine. The best way to improve fire safety is to consider all fire risks in design stage and to develop maintainability of electric cabling and ...

Loads and stresses—the real cause of failures in surface ...

On large mining machines, most failures are initiated by fatigue. In many failures the material properties are considered satisfactory, and the root cause of the failure lies in the loads, stresses, and high number of cycles. Final failure occurs when the combination of nominal, dynamic, and residual stress exceeds the capacity of the component.
