5.5. Spontaneous Combustion Control

Spontaneous combustion is one of the major safety concerns in underground coal mining. Current technologies are successful except in early detection and locating of spontaneous combustion. A number of options have been suggested for further development in this report.

Current leading technologies successfully developed and applied in some of APP countries include:

  • radon based remote locating technology

  • fire suppressant gels or colloids and their injection system.

R & D requirements to address the gaps in spontaneous combustion control technology and to meet future needs in APP countries include:

  • early detection

  • monitoring and locating deep and inaccessible goaf heatings.

China is leading in the current technologies to manage spontaneous combustion of coal. It is suggested that the technologies be trialled in other APP countries through demonstration projects. For the future R & D projects in early detection and remote monitoring and locating of heatings, it is recommended that APP countries collaborate to advance these technologies.
