Overview of active explosion barrier systems for underground coal mines

This paper review the main concepts ruling the design, implementation and performance of active explosion barrier systems for underground coal mines in the USA. The document examines the parameters needed for the design of this type of system, such as pressure and flame speed and temperature. The document also discusses the available solutions for gassy mines and the concepts behind the selection of a specific barrier application. This might be machined mounted, in a longwall or roadway active explosion barrier systems. The paper includes a review of active explosion barrier systems developed in the USA, and other counties. The paper provides an overview of the current status of this technology in the underground coal mining industry in the USA, and the possible implementation of such systems. An overview of the status of those systems in various mining countries including Australia, China, South Africa, Canada and in Europe is also included in the paper. The paper concludes with the identification of the future work needed for the successful implementation of the systems in several conditions to enhance the safety of underground coal mine operations and to provide more tools to the miners for their safety.
