一些国家正积极调查利用结晶岩体作为放射性核废料最终处理场所的可行性。作为加拿大废核燃料处理计划方案评价的一部份,对马尼托巴东南部的Lacdu Bonnet岩体进行了一次多学科调查研究。在这个岩体中正准备处置一些密封的放射源或示踪同位素。高分辨率地震发射波测量结果和从几个深钻孔取得的资料一起显示出,直到800 m深度的岩体内部存在着有影响的水平裂隙带。综合解释地震数据和选出的测井资料后发现,有热水沿主要裂隙带上涌。在岩体中寻找合适的放射性废料处置场地时,不能不把主要裂隙带的渗透性能和
Some countries are actively investigating the feasibility of using crystalline rock as a final disposal site for radioactive nuclear waste. As part of the evaluation of the Canadian program of spent nuclear fuel disposal programs, a multidisciplinary investigation of the Lacdu Bonnet massif in southeastern Manitoba was conducted. Some sealed radioactive sources or tracer isotopes are being prepared in this rock mass. High-resolution seismic emission wave measurements, along with data from several deep boreholes, show that there are horizontal fractures within the rock mass up to depths of 800 m. After comprehensively analyzing the seismic data and the selected logging data, it is found that hot water floats along the main fracture zone. In the rock mass to find a suitable disposal site for radioactive waste, can not but the permeability of the main fracture zone and
