感温探测防灭火系统在井下运输系统火灾防治中应用

An application of a heat detector based fire protection system for the fire control of an underground transport system

为了提高带式输送机安全保障能力,提出将感温探测防灭火系统对带式输送机运行进行监测,通过感温光纤实时监测带式输送机周围异常温度并定位异常温度点位置,喷淋灭火根据感温光纤定位的结果进行定点喷淋,从而避免由于带式输送机运行异常导致的火灾事故扩大。并详细对感温探测防灭火系统工作原理、结构组成以及现场应用情况进行阐述。研究成果可为其他矿井运输系统防灭火工作开展提供一定借鉴。

To improve the safety level of belt conveyors,it was proposed to use heat detectors: optical fiber heat detectors were installed along the conveyor to detect temperature abnormality and locate the fire position;sprinkling units were then activated corresponding to the fire locations,to prevent any conveyor induced fire from deteriorating. The article also elaborates on the working principles,composition,and field application of the heat-detector-based fire protection system. The study serves as a reference for the fire protection of other mine transport systems.
