在英国煤矿应用循环通风方式的设想由来已久,尽管当时被认为是危险的,而且法规禁止这样做。直到新的粉尘规程开始实施现代监测设备得到应用时,才开始进行循环工艺的研究。本文扼要地列举了第一个局部循环系统在降低独头工作面的温度、湿度,尤其是粉尘浓度方面的效益。随着循环技术和监测设备方面的进一步研究和发展,本文详细地叙述了英国煤炭威尔莫斯(Wearmouth)矿,在实施完全的区域循环系统时所采用的第二套工作系统。
The concept of circulating ventilation in the UK coal mines has been around for a long time, though it was considered dangerous at the time, and regulations prohibit doing so. Until the new dust regulations began to implement the application of modern monitoring equipment, began the study of recycling process. This article gives a brief summary of the benefits of the first partial circulation system in reducing the temperature, humidity, and especially dust concentration in a single-sided work surface. With further research and development on recycle technology and monitoring equipment, this article details the second working system used by the British coal mine Wearmouth when implementing a complete regional circulatory system.
