| 摘 要： | 对可供地浸法开采的５１２铀矿床镭－氡放射性平衡规律进行初步研究表明，在对该矿床钻孔施工过程中，由于泥浆压力的存在，使镭－氡放射性平衡遭到破坏，严重地降低了伽玛测井的伽玛照射量率，使按伽玛测并确定的储量计算参数不准确。为此，作者对这一平衡破坏规律进行了初步研究，确定了储量计算参数的镭一氡平衡破坏修正值，既消除了伽玛测井的影响因素，又增加了２０％的远景储量。建议在今后对该矿床进一步工作时，对该平衡破坏规律采用岩芯取样为主，同时辅以适量的专门物探参数观测孔进行验证的研究方案。

| Abstract: | A preliminary study of Uranium deposit 512 shows that the Ra-Rn readioactive balance was destroyed due to the mud pressure, resulting in the decrease of gamma scanning rate and inaccuracy of reserve calculation parameters. A revised vain-e was determined:or the lost balance of Ra-Rn. de the affecting factors of gamma well loggihg were released and 20% prospective reserve was added. A suggestion was put forward that core sampling be mainly applied, coupled with a certain amount of specific geophysicAI parameter observation, holes. |
