一、引言矿用安全帽灯(以下简称矿灯)的设计与制造应能满足两方面的要求: 1.具有较好的照明性能:如较长的点灯时间,较轻的重量,较大的单位重量光输出及较高的照度等指标,以满足矿工在井下工作的需要,为提高劳动生产效率提供条件。 2.具有可靠的安全性能:由于矿灯是在有爆炸性气体混合物的煤矿井下使用,因此,其安全问题更为重要,矿灯必须具备可靠的安全性能,以确保矿工的生命安全及煤矿生产安全。目前我国矿灯的制造与检验是依据GB1336—77《防爆电气设备制造检验规程》附录三“蓄电池头灯制造检验技术文件”。此文件过于简单,无论是技术要求还是检验方法都 I. INTRODUCTION Mining helmet lamp (hereinafter referred to as miner’s lamp) design and manufacture should be able to meet the requirements of two aspects: 1. Has better lighting performance: such as a longer lighting time, lighter weight, larger units Weight light output and high illumination and other indicators to meet the needs of miners in the underground work, in order to improve labor productivity and provide conditions. 2. Reliable safety performance: Because the miner’s lamp is used under coal mine with explosive gas mixture, the safety issue is more important. The miner’s lamp must have reliable safety performance to ensure the life safety of miners and the safety of coal mine production. At present, the manufacture and inspection of miner’s lamp in China are based on the appendix III of “Test Procedures for the Manufacturing of Explosion-proof Electrical Equipment” of GB1336-77. This file is too simple, both technical requirements and test methods are
