Research into Reversion of Airflow with Multi-ventilation Shafts During Mine Accidents
Reversion of airflow is a common practice to contain the accidents, especially the methane or fire accidents, happened in coal mines. Since the ventilation network in a developed coal mine is very complex, there are certainly many combinations for local reversion of airflow within working panels. This paper, using Datong Yungang coal mines as an example to study the airflow control technology for mine accident control and management. The trials of reversion of airflow are under a multi-ventilation shafts (5 intake shafts and 6 return shafts) conditions with a very complex system. The determination of reversion of airflow during mine rescue period is fully examined in detail from all aspects in terms to minimize the losses and saving lives of mine rescuers. The field trials results show that the improvement of stability and reliability of ventilation system plays an important part in mine ventilation during accidents. During mining rescue, the traditional empirical approaches for decision making some times can not achieve the goal and a real-time data based dynamic decision making process is required.
