摘要
煤炭资源整合设计的特点是井筒多且剩余资源／储量距现有工业场地较远。为了安全经济合理的开采所剩煤炭资源，多数情况是新开掘一个主井，现有若干井筒根据具体情况确定一个作副井，二个作专用回风井。笔者对设置专用回风井对煤矿生产本质安全型的作用作了分析，并就在煤炭资源整合矿井设计中留设专用回风井的必要性进行了论述。
The characteristic of coal resources conformity mine is that there are lots of shafts, but the surplus resources are a little far from industrial site. In order to mine the surplus resources safely and economically, a new main shaft is initated and an auxiliary shaft is determined in most cases, one is used as a special air shaft. In this paper, the function of special air shaft in intrinsically safe of coal mine is analyzed and leaving special air shaft in the design of resources conformity mine is discussed.
