我矿所用的矿灯,均为天津、北京等地产品。电磁锁一般使用几个月后就易自开或不用专用工具就能打开,给煤矿安全带来了隐患,特别对超级瓦斯矿井来说,更为有害。多年来,为解决这一安全隐患,虽经多次研究改进,始终也没有得到很好解决。我矿二井矿灯班革命工人,怀着深厚的无产阶级感情,反复试验,终于在1971年6月创造成功安全灯锁。他们用土办法,简单机具改制了1700多台,从1971年9月投产至今,实践证明效果良好。灯锁日损坏率仅为1‰。其构造和制做过程如下。
Miner’s lamp used in mine are all products of Tianjin and Beijing. Electromagnetic locks generally use a few months after the easy to open or without special tools can be opened, bringing hidden dangers to the safety of coal mines, especially for super-gas mines, more harmful. Over the years, in order to solve this potential safety hazard, it has not been well resolved despite repeated studies and improvements. I mine mine shaft lamp revolution workers, with deep proletarian feelings, repeated tests, and finally in June 1971 to create a successful safety light lock. They used the indigenous methods and simple machines to reform more than 1,700 units, putting it into operation from September 1971 to the present and have proved to be effective. Light lock damage rate of only 1 ‰. Its structure and making process is as follows.
