“…As a result, a key element determining the usability of this mining method and a major barrier to its widespread adoption is the permeability of the uranium deposit [122]. In situ leaching techniques are typically considered unsuitable for uranium deposits with low inherent permeability (<0.5 m/d) [123]. To address this challenge, many scholars have concentrated their studies on permeability modification techniques for low-permeability uranium deposits, thereby broadening the application of in situ leaching [123][124][125][126].…”

“…In situ leaching techniques are typically considered unsuitable for uranium deposits with low inherent permeability (<0.5 m/d) [123]. To address this challenge, many scholars have concentrated their studies on permeability modification techniques for low-permeability uranium deposits, thereby broadening the application of in situ leaching [123][124][125][126]. While hydraulic fracturing, a widely used approach for enhancing permeability in oil and gas reservoirs [127,128], has been proven ineffective for uranium deposits [124], blasting-enhanced permeability (BEP) has emerged as a promising and effective technique for this specific context [125].…”

“…On the other hand, physical stimulation involves applying pressure to induce damage and fractures in the reservoir, thereby increasing its permeability . This pressure can be either static or dynamic. , For instance, hydraulic fracturing, as a representative of static methods, applies high-pressure water flow to the reservoir to create large fractures along the maximum principal stress direction, gathering oil and gas within a hundred-meter range . Hydraulic fracturing creates large and singular fractures, which can enhance the permeability of the reservoir, yet it remains unfavorable for extensive permeation of gas. , Additionally, hydraulic fracturing is associated with long construction periods, high resource consumption, and environmental pollution. , For a long time, measures such as high-energy gas fracturing and deep hole presplitting blasting have been taken to increase reservoir permeability through dynamic shock wave methods, which can promote the generation of more small fractures and are more conducive to the large-scale migration of reservoir fluids.…”

“…The common method to improve the permeability of low-permeability reservoirs is reservoir stimulation, including the hydraulic fracturing method [ [10] , [11] , [12] , [13] , [14] ], pressure-relief method [ [15] , [16] , [17] ], chemical stimulation method [ [18] , [19] , [20] ], high/low-thermal shock method [ 21 , 22 ] and blasting method [ 23 , 24 ], which have been applied in unconventional oil/gas development fields. For the LPSUD, reservoir stimulation methods of blasting-enhanced permeability (BEP) [ 25 , 26 ] and acidizing-enhanced permeability (AEP) [ [27] , [28] , [29] , [30] ] have carried out several pilot tests in China and the injection rate of wells has improved by 118% [ 31 ].
