验证孔部署施工是“煤铀兼探”新思路指导下的砂岩型铀矿找矿工作中最为关键的一环,直接决定了找矿成败。为达到既能提高验证孔见矿率又能初步指明铀矿找矿方向的双重目的,通过对西南首批优选靶区中滇西户撒盆地6口验证孔不同部署方法的验证效果对比,在以往原位验证法基础之上,创新性提出通过绘制沉积相带展布和煤田钻孔分布图,以统计的各沉积相带中异常钻孔率为指标进行原位选取的验证孔部署优化建议。
The verification hole deployment construction is the most crucial part of the prospecting work for sandstone-type uranium deposits under the guidance of the new idea of “coal, uranium and exploration”, which directly determines the success or failure of prospecting. In order to achieve the dual purpose of improving the seepage rate of proven pores and initially identifying uranium prospecting direction, the comparison of the verification results of different deployment methods of six verification wells in the first batch of selected targets in southwestern Yunnan, In the past, based on the in-situ verification method, we propose to optimize the deployment of holes by plotting sedimentary facies belt distribution and coalfield borehole distribution, taking the abnormal borehole rate in each sedimentary facies as an indicator .
