在我国的《煤矿安全规程》中有着详细的关于在煤层的掘进过程中在巷道之间的连接上面,必须做好相关安全预防工作,其中包括瓦斯、煤尘和放炮等等。由于是在地下较深处煤层工作,所以在掘进贯通的时候很容易造成由于气压和风压的异常导致管道内部相应的变化。由于这些变化形式多样,所涉及的相关方面太多,导致在煤层掘进上贯通后危险的防治工作上,一直是困扰煤矿技术人员的技术难题。所以,对于在掘进时管道的贯穿前做的安全防治工作就凸显的尤为重要了,他将直接关系到挖掘人员的人身安全。
In China’s “Coal Mine Safety Regulations” has a detailed on the connection between the roadway in the coal seam during the tunneling process above, we must do a good job of safety precautions, including gas, coal dust and blasting and so on. Because it is working underground deeper coal seam, so when the tunneling is very easy to cause due to abnormal pressure and wind pressure led to the corresponding changes within the pipeline. Due to the diversity of these changes, there are so many related aspects involved that it has always been a technical problem for coal mine technicians to prevent and control post-mortem coal seam mining. Therefore, it is especially important for the work of prevention and control of pipelines during excavation that they will be directly related to the personal safety of the diggers.
