The Application of Dynamic Pressure Balancing Technology in Isolated Island Goaf Fire Prevention and Extinguishing

Due to the polytrope of airflow in different stages, the working faces around the isolated island goaf need to adjust fire prevention and extinguishing scheme according to the changes of pressure energy differential. The grading fire prevention and extinguishing design is made by using dynamic pressure balancing fire prevention and extinguishing technology, which effectively prevents the occurrence of spontaneous combustion.
