摘　　要：The trigger action response plans （TARPs） are inherent to managing the multiple hazards such as： high gas content with multiple coal seams, high spontaneous combustion （sponcom） propensity, heat and ventilation, TARPs aim to provide assurance and guidance when the situation deviates from the original plan or there is a change conditions that could he hazardous, Over the years, learnings from various incidents has continuously required the coal operations to re-visit the TARP trigger values that were based on historic data or based on guidance values from the industry, In most cases, the background to the basis of TARP statistical data, viz,, average, maximum, hourly, daily for the monitoring or sampling location is also unknown, Introduction of real-time monitoring devices to monitor the gases and airflows has provided greater understanding of the hazard scenarios and their controls, This paper analyses the carbon monoxide data from operating longwall mines and compares these with the historic trigger values to understand the changes and determine improvement opportunities while setting trigger levels in the TARPs, As an example of setting trigger values, those used in during the sealing of a panel are explored in terms of setting values based upon the sampling location and the level of risk, It is envisaged that the learning＇s shared herein would further enhance the understanding and management of multiple hazards in Australian coal mines,The trigger action response plans(TARPs) are inherent to managing the multiple hazards such as: high gas content with multiple coal seams, high spontaneous combustion(sponcom) propensity, heat and ventilation. TARPs aim to provide assurance and guidance when the situation deviates from the original plan or there is a change conditions that could be hazardous.
