Explosion prevention and protection in underground mines - Protective systems - Part 4: Automatic extinguishing systems for road headers
This document lays down requirements for automatic explosion extinguishing systems for roadheader machines (selective cut heading machines) in roadheader drivages where these systems automatically detect the initial phase of a firedamp explosion which has been initiated by the cutter head of a roadheader machine and extinguish it at the roadhead in such a way that the roadway drivage team is not put at risk. This document does not lay down any requirements for the fighting of fires at the roadhead.
The automatic explosion extinguishing system for roadheaders is an autonomous protective system designed in accordance with Directive 94/9/EC.

device that is triggered by changes in one or more parameters, e.g. temperature and/or radiation, caused by a developing explosion.
4 General requirements 4.1 General Automatic explosion extinguishing systems for roadheaders essentially comprise the following co-ordinated components:
sensors for explosion ignition detection; ¾ extinguishing agent containers for explosion fighting; ¾ control system for monitoring the individual components and their combined effect as well as the triggering of the extinguishing system (electronic control and operating unit); ¾ power supply and emergency power supply. The number and configuration of the individual components are determined by the type of machine and by the roadway cross-section to be protected. EN 13463-1 and EN 60079-0 shall be applied. 4.2 Functional requirements 4.2.1 General All components are to be designed for high operating reliability in accordance with the “fail-safe” principle. A high level of protection against incorrect triggering shall be ensured by means of a selective response action and minimum sensitivity to external interference factors. Appropriate protection devices are to be used to protect the components from unauthorized external interventions. If the roadheader has an automatic explosion extinguishing installation, the roadheader shall be equipped with a compulsory interlock. All electrical equipment shall be of class M1. The system is designed for an ambient temperature of – 20 °C to 40 °C. A degree of protection of at least IP 54 is required.
SIST EN 14591-4:2007
EN 14591-4:2007 (E) 6 4.2.2 Sensors Explosion-detection sensors shall operate on the basis of one of the physical quantities related to the event of an explosion (e.g. type of flame, radiation). In this respect, full use shall be made of the maximum response speed and sensitivity.
The monitoring range of the detection sensors shall be fixed in such a way that the system only detects those events that have to be controlled. The events to be detected are explosions that have been caused by the cutter head of the roadheader machine and which are initiated in the vicinity of the machine, but not fires occurring outside the cutting zone. The functional reliability of the sensors shall not be impaired by local factors (dust, water/mist, construction materials, etc.). The function of the sensors shall be proven by means of a function test with a methane flame. 4.2.3 Extinguishing agent co
