同位素测氡技术在煤矿火源位置探测中的应用

Application of Isotope Radon Measurement in Detection of Coal Mine Fire Location

摘要: 分析了目前常用的火源探测技术适用性，针对榆家梁煤矿周边的小窑火区浅埋藏、地表无植被的特点，选用了同位素测氡技术进行火源探测。对探测出的异常区域采取钻孔注浆、黄土覆盖压实、构筑隔离带和挡火墙等措施后，小窑火区得到有效治理，验证同位素测氡法探测火区高温点的准确性，消除了小窑火区对榆家梁煤矿安全生产的威胁。

Abstract: The article analyzes the applicability of current common fire source detection technology. Aiming at the characteristics of shallow buried and the ground without vegetation in small coal mine fire area around Yujialiang Coal Mine. The study chose technology of isotopic radon measurement to detect fire. It took drilling grouting, compaction with covered loess, building buffer zone and a blocking firewall and other measures for the abnormal area. The small coal mine fire area has been effectively controlled. It verified the accuracy of isotopic radon measuring method in detecting hot spots in the fire area, and eliminating the small coal mine fire zone threat to safety production of Yujialiang Coal Mine.
