煤矿井下火灾的扩大蔓延可引起全矿井毁灭的重大灾害。为防止这类事故,公害资源研究所九州煤矿技术研究中心根据煤炭和石油应付措施的特殊拨款,从1977年开始继续进行了防止井下火灾扩大技术的研究。到目前为止,在全部研究方法中水喷雾带法仍是防止井下火灾扩大蔓延的最实用和最有效的方法。此法既经济又简单,容易被现场引用。为探求水喷雾带设置标准的基础资 The expansion and spread of underground coal mine fires can cause major disasters that destroy the whole mine. To prevent such accidents, Kyushu Coal Mine Technology Research Center of Institute of Pollution Resource continued its research on preventing underground fire expansion technology from 1977 on the basis of special appropriation for coal and oil response measures. So far, the water spray zone method is still the most practical and effective way to prevent the spread and spread of downhole fire in all the research methods. This method is both economical and simple, easy to be quoted on site. To explore the water spray with a standard set of basic resources
