探测自燃火源位置的多重方法联用技术

Multi-method combination technology for detecting spontaneous combustion location

为了探测霍尔辛赫煤矿矸石场自燃火源位置,在分析各种火源探测方法优缺点的基础上,利用红外成像仪对矸石场进行现场勘察,大致确定其温度及气体异常范围。然后利用同位素测氡法、气体探测法与现场精细温度测量等多种方法对矸石场进行实测,结果表明:不同方法检测到的异常区域大致一致,通过对比,说明了各种火源探测方法各有优缺点。通过各种方法对火源的探测,进行对比分析,得出了对霍尔辛赫煤矿矸石场自燃火源位置探测应采用以同位素氡探测法为主,红外热成像法、气体探测法与测温法为辅的多重方法联用技术,并进一步划分了火区范围和面积。

In order to detect spontaneous combustion location in the gangue yard of Huoerxinhe Coal Mine,based on the analysis of the advantages and disadvantages of various fire detection methods,the gangue yard was detected respectively by infrared thermal imaging method,isotope radon method,gas detection method and on-site fine temperature measurement method.The results show that the anomalous areas detected by different methods are roughly the same.Through comparative analysis,it is concluded that the multi-method combination technology should be adopted to detect spontaneous combustion location in the gangue yard of Huoerxinhe Coal Mine,which is mainly based on isotope radon detection method and supplemented by infrared thermal imaging method,gas detection method and temperature measurement method.
