| 摘 要： | 煤田火区的精准探测是目前煤田火区探测的发展方向，从传热传质学角度详细阐述了汞迁移机理，建立了半无限大介质和温度影响下汞的迁移方程。介绍了RA-915测汞仪的原理，并使用该仪器在五虎山煤矿10号火区进行了现场测试，对10号火区汞浓度进行了数值模拟，确定了汞浓度异常区域。测汞法为煤田火区探测开发了一种新的方法，可以指导煤田火区探测，实现煤田火区高温异常区域的超前预测预报，及时采取有效措施消灭煤田火灾火源点。

| Abstract: | The accurate detection of coal fire area is the development direction of coal fire area detection at present.The migration mechanism of mercury is described in detail from the perspective of heat and mass transfer，and the migration equation of mercury under the influence of semi infinite medium and temperature is established.he principle of RA-915 mercury analyzer is introduced.The instrument is used for field test in No.10 fire area of Wuhushan Coal Mine.The mercury concentration in No.10 fire area is numerically simulated，and the abnormal area of mercury concentration is determined.Mercury measurement method has developed a new method for coalfield fire area detection，which can guide coalfield fire area detection，realize the advance prediction of high temperature abnormal area in coalfield fire area，and take effective measures to eliminate the fire source of coalfield fire in time. |
