《煤矿安全》1980年第7期介绍了“延时风电闭锁”一文。我们学后认为:涟邵局利民煤矿介绍的延时风电闭锁的经验很好,电气线路完善,值得推广。利用 ABD—1型瓦斯报警断电仪配合安装延时风电闭锁装置,能有效地达到前期报警、及时断电、瓦斯浓度降低到安全浓度后才能送电的目的。对于确保掘进工作面,特别是有煤与瓦斯突出的掘进工作面的安全生产,有着重要意义。
“Coal Mine Safety” 1980 the seventh period introduced “delay wind power lock” article. Our post-school think: Lian-Shao Li Limin coal mine introduced the experience of delayed wind power lockout well, the electrical circuit is perfect, it is worth promoting. ABD-1-type gas alarm power meter with delay wind power installation delay device, can effectively reach the early warning, timely power, gas concentration reduced to a safe concentration before the purpose of power transmission. It is of great significance to ensure safe production of heading face, especially for heading face with coal and gas outburst.
