摘 要:碳硅泥岩型铀矿床采用常规方法不易开采。依据钻孔水力开采工艺特点,结合二连盆地某碳硅泥岩型铀矿床的工程地质条件,在模型试验相似理论基础上进行了碳硅泥岩型铀矿床钻孔水力开采模型相似研究。基于所推导的模型试验相似准则,通过理论分析及试验,实现了模型试验的几何条件、边界条件、高压水射流荷载及材料相似。研究结果可为碳硅泥岩型铀矿床水力开采提供依据和试验基础。The carbonaceous-siliceous-argillaceous rock uranium deposit has an important position in Chinese uranium resources,but it is difficult to be exploited by conventional methods.Therefore,according to the characteristics of drilling hydraulic mining and combination of the geological conditions of carbonaceous-siliceous-argillaceous rock uranium deposit in Erlian Basin,based on the similarity theory of mode test,the similarity rate of the model test of drilling hydraulic mining in the carbonaceous-siliceous-argillaceous rock uranium deposit is carried out.Through theoretical analysis and experimental research,the geometric condition,boundary condition,similarity of high pressure water jet load and similar materials are achieved.The results of the similarity criterion of the derived model can provide scientific and experimental basis for mining of carbonaceous-siliceous-argillaceous rock uranium deposit.
