An investigation on emergency response system during Anjan hill coal mine disaster using control task analysis – a cognitive approach

Abstract

The accidents due to gas and coal dust explosion are one of the most common and serious accidents in underground coal mines. A lot of different scientific and physical indications and signs alarms before any accidents. Disasters management is both reactive and proactive. The proactive management deals with various steps taken to prevent and eliminate any disaster. Whereas, reactive management, on the other hand, deals with the actions taken to reduce the damage caused by a disaster, mitigate sufferings, take up recovery measures, organize rehabilitation, bring normalcy of different operations in the mine, disseminate prompt information to relatives of the victims, civil authorities, print and electronic media and people living nearby. Therefore, in any emergency situation the emergency response system (ERS) plays the most crucial part. An efficient ERS can potentially save an emergency situation to turn into a disaster or serious accident. In this paper, a case study conducting control task analysis (CTA) to investigate into the emergency response system during Anjan hill coal mine disaster is presented. Inquiry reports of Anjan hill coal mine disaster has been used to identify the problem and know the current state of the system. Results of CTA are used to identify constraints in the system. The analysis has brought out recommendations to improve EMS.
