| 中文摘要: |
| 镭氡平衡系数是砂岩型铀矿勘查工作中的一项重要参数,及时开展该参数的研究对指导铀矿勘查评价、资源量估算等具有重要的意义。目前,镭氡平衡系数主要由两种方法确定,即分析对比法和物探参数孔观测方法。引入非线性渐近回归方程对物探参数孔观测数据进行曲线拟合,对蒙其古尔铀矿床西山窑组下段镭氡平衡系数进行了计算及研究,并对计算结果进行了对比与评价。两种方法在砂岩型铀矿镭氡平衡系数计算中都非常重要,物探参数孔观测法计算的镭氡平衡系数结果准确性更高。利用非线性渐近回归计算镭氡平衡系数,可以有效地避免由于对观测值最小值与最大值的估算不准而带来的误差,结果更为合理。 |
| 英文摘要: |
| The equilibrium coefficient of radium and radon is an important parameter in the exploration of sandstone-type uranium deposits.At present, the equilibrium coefficient of radium and radon is mainly determined by two methods, namely the geophysical parameter drilling observation method and the comparison method between the results of radium content analysis and γ logging interpretation.The nonlinear asymptotic regression equation is introduced to curve fit the observed data of geophysical parameter drilling, and the radon equilibrium coefficient of the lower section of Xishanyao formation of Mengqigur uranium deposit is calculated and studied, and the calculated results are compared and evaluated.Both methods are very important in calculating the equilibrium coefficient of radium radon in sandstone-type uranium mines, and the result of geophysical parameter drilling observation method is more accurate.Using nonlinear asymptotic regression to calculate the equilibrium coefficient of radium and radon can effectively avoid the error caused by inaccurate estimation of the minimum and maximum observed values, and the results are more reasonable. |
