作者开发了煤矿开采安全的计算机监测系统。该系统采用的主机是一台小型的科学运算机。有些传感器和传输设备是为该系统专门设计的。但是,也能使用那些输出信号范围适合的普通传感器。由于引进了计算机,该系统通过计算机又增加了三个基本功能:i)时间序列数据的处理。ii)散装传感器的数据连锁。iii)监测项目的多样化。利用这些功能,该系统便能进杆灾害预测或预防。连续监测CO集中梯度,可防止自燃或发火。对正常情况下CO值的基本变化进打数理统计和时间延续试验,以消除某些干扰(如放炮)所产生的影响。提出了一种预测瓦斯和煤突出的新方法。该方法的基础是观察证实:瓦斯抽放系统和风巷内CO含量有着紧密的联系。此建议性方法还有待实践验证。瓦斯爆炸的预防是通过监测CH4数据来实现的。如今,日本的所有煤矿都在引进本文所介绍的改进性建议,即采用计算机集中监控系统。
The author has developed a computer monitoring system for coal mining safety. The system uses the host is a small scientific computer. Some sensors and transmission equipment are specially designed for this system. However, it is also possible to use general sensors with a suitable output signal range. Due to the introduction of a computer, the system adds three more basic functions through the computer: i) processing of time series data. ii) Data Linkage of bulk sensors. iii) Monitor the diversification of projects. With these capabilities, the system can predict or prevent disaster. Continuous monitoring of CO concentration gradient can prevent spontaneous combustion or ignition. The basic changes in CO values under normal circumstances into the mathematical statistics and time delay test to eliminate some of the interference (such as blasting) the impact. A new method of predicting gas and coal outburst is proposed. The method is based on the observation that the gas drainage system is closely related to the CO content in the wind tunnel. This proposed method has yet to be proven. Gas explosion prevention is achieved by monitoring CH4 data. Today, all coal mines in Japan are introducing the improved recommendations presented in this article, using a centralized computerized monitoring system.
