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。 This paper mainly introduces the simulation test of the “three times” exploitation of the loose uranium deposit comprehensive system, and through the experiment of cementing downwards to the cement filling method. According to the observation results of rock pressure displacements, hydrological conditions, the movement of surface and buildings, Under the "mining test to take some of the technical measures can effectively protect the topography and achieved good economic and social benefits.
