摘要
基于对两淮煤田煤系地层所测定的32块岩石样品的放射性生热元素(U、Th、K)结果,计算得出各个岩石样品的放射性生热率的大小;并全面报道了两淮煤田岩石放射性生热率参数及其特征,从多方面分析影响其大小的因素,研究结果表明:两淮煤田煤系地层岩石放射性生热率变化范围为0.58μW/m~3~3.21μW/m~3,平均值仅为1.68μW/m~3;放射性生热率与岩性、埋藏深度、地层时代相关密切,同时岩石放射性生热对区内地表热流也有一定的贡献。
Based on the measured results of radioactive heat generation elements,including U,Th,and K,the heat generation ratios of 32 rock samples in coal measures of Huainan and Huaibei coal field were calculated respectively.Their influential factors were studied with the parameters and features of the ratio in many respects.The results show that the ratio ranges from 0.58 μW/m~3 to 3.21 μW/m~3,1.68 μW/m~3 on average,which is closely correlated with lithology,buried depth,and strati-graphic age.Besides,the radioactive heat generation contributes to the surface heat flow in the area.
