同位素测氡技术在矿井火区探测中的应用

Application of isotope radon measurement technology in the detection of mine fire area

针对补连塔煤矿煤层浅埋深、地表无植被的特点,选用了同位素测氡技术进行火源探测。对探测出的氡气异常区域采取井上下综合火区治理措施,采空区高温得到了有效治理,验证了同位素测氡法探测火区高温点的准确性,消除了补连塔煤矿采空区高温对矿井安全生产的影响。

According to the characteristics of shallow buried coal seams and surface with no vegetation in Bulianta Coal Mine,the isotopic radon measurement technique was used to detect the mine fire source. To the radon anomaly region,by taking the integrated fire control measures,the high temperature zone in gob was controlled,the accuracy of radon measurement technology in detecting high temperature point was verified,and the influence of high temperature zone in gob to mine safety production was eliminated in Bulianta Coal Mine.
