摘要
围绕孤岛采空区进行开采的工作面,由于其风流在不同阶段的多变性,需要根据压能的变化情况及时调整防灭火方案。利用动态均压防灭火技术,进行了分阶段防灭火设计,有效地防止了煤炭自燃的发生。
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 occur- rence of spontaneous combustion.
