Comments for: The Technical Study Panel on the Utilization of Belt Air and the Composition and Fire Retardant Properties of Belt Materials in Underground Coal Mining Dear Panel Members: I would like to present the following information for your review and consideration on your evaluation of “Utilization of Belt Air and the Composition and Fire Retardant Properties of Belt Materials in Underground Coal Mining.” The direction of the ventilation current and the fire fighting capabilities must be considered in your report. The risks involved with each particular case are different and higher risk systems should require increased protections for the miners. The ventilation flow can be either towards the mining section, away from the mining section or split in some manner. I have personally witnessed or have been involved with each of these scenarios over the years. Each has key areas for consideration in regards to early warning, escape and fire fighting capabilities. I hope you will give each of these considerations within your report. Flow towards the mining section: Traditional fire fighting and fire warning devices are installed form outby to inby as the section develops. With the flow of air in this direction, alarm situations are more recognizable; traditional fire fighting capabilities are utilized; and the fresh air is at the firefighters back. CO alarm stations are usually sequentially numbered on installation and it is easy ...
