针对马营煤矿东部4号煤层小煤矿采空区遗煤自燃问题,利用同位素测氡法对采空区进行火区探测,查明共有13个火区,总面积约为27513m2,并确定了火区的方位及发展趋势。探测结果与前期普查结果比较吻合,验证了测氡法应用于马营煤矿东部井田火区区域探测的可行性,同位素测氡法探测结果为制定小煤矿采空区火区治理技术方案及措施提供了技术依据。

According to the left coal spontaneous combustion problem of the goaf in a small coal mine in No.4 seam at the east part of Maying Mine, an isotope rad on measuring method was applied to the firing zone detection of the goaf.There were 13 firing zones detected in total with the total area of 27 513 m2 and the position and development tendency of the firing zones were determined.The detected results and the previous general investigated results were quite fitted.Thus the feasibility 0 f the radon measuring method applied to the regional detection of the firing zones in the eastern minefield of Maying Mine was confirmed.The detection results of the is otope radon measuring method could provide technical basis to make the technical control plan and measures of the firing zone in the goaf of the small mine.
