煤矿勘探坑道最大的特点是瓦斯含量大，由于瓦斯的集聚很容易引起爆炸事故。由于我们严格执行了党的安全生产的方针，大力发动了群众，加强了对职工的安全教育，做到人人管生产，个个管安全，并采取了一系列的有效措施，自58年3月以来我队一直保持着生产安全双跃进并取得了很大成果。现将其经验与体会介绍如下：一、瓦斯的性质与特征 煤矿巷道中爆炸瓦斯的主要成分是沼气（CH_4），有时混有二氧化碳、氮、
The biggest characteristic of coal exploration tunnel is gas content, due to the accumulation of gas can easily cause an explosion accident. Since we strictly implemented the principle of the party’s safe production, we have vigorously mobilized the masses, strengthened the safety education for staff and workers, ensured all the people are in charge of production, managed everything safely and took a series of effective measures. Since 58 Since January, our team has maintained a double leap forward in production safety and achieved great results. Now its experience and experience are described below: First, the nature and characteristics of gas Coal mine explosion in the main gas channel is methane (CH_4), sometimes mixed with carbon dioxide, nitrogen,
