Discussion on Underground Layout Scheme of Model JSG-8 Fire Monitoring System with Beam Tube

The paper introduced working principle and structure of model JSG-8 fire monitoring system with beam tube. For problem of difficult collection of gases of coal spontaneous combustion in coal face and goaf, it discussed layout scheme of beam tube monitoring points of the system in coal face and goaf in details, and indicated that it need consider influence degree on coal face production when making layout of beam tube monitoring points in coal face.
