在一项使用北莱茵——威斯特伐伦州政府资金、由北莱茵——威斯特伐伦州煤炭管理局执行的研究计划中,研究了矿井空气的成份,以便查明其中是否含有那些具有一定浓度、而且影响瓦斯测量仪(特别是热效式瓦斯测量仪)的检测灵敏度的物质.研究计划的进一步目标是改进火灾的预测和借助于程序计算机监视瓦斯的涌出.此外,还研究了爆炸烟气逆风流的传播及瓦斯云雾在爆源与出风井筒间的稀释.在各个部门所进行的研究的目标是:改善对矿井空气中有害或危险气体的监测;判别在井下安设的瓦斯警报 In a research project funded by the North Rhine-Westphalia government funded by the North Rhine-Westphalia Coal Authority, the composition of the mine air was studied to find out if it contained Those that have a certain concentration and affect the detection sensitivity of gas gauges, especially thermal effect gas gauges, Further goals of the research project are to improve the prediction of fires and to monitor the emission of methane gas by means of a computer program. Studied the spread of reverse flue gas flow and the dilution of gas clouds between the blast source and the wellbore.The objectives of the research carried out in various sectors were to improve the monitoring of harmful or dangerous gases in the mine air and to determine the safety of the mine Set the gas alarm
