铀矿床“三下”开采模拟试验

本文主要介绍松软铀矿床综合体系“三下”开采的模拟试验,通过下向胶结充填采矿方法试验,并根据地压岩移、水文状况、地表及建筑物移动变形等的观测结果,论证模拟“三下”开采试验所采取的一些工艺技术措施能有效地保护地形地物,取得了良好的经济效益和社会效益。

SIMULATED MINING TEST OF URANIUM ORE DEPOSIT UNDER RIVER AND BUILDINGS

The simulated test of mining the loose and soft uranium deposit under river and buildings is presented in this paper .Using the underhand cut-and-fill mining method and on the basis of investigation on the rock pressure change, the hydrological data and the deformation of surface and buildings, the technical measurements taken for the simulated test have been demonstrated with effective protection of surface and buildings and good economical and social effects.
