Bayinqinggeli uranium deposit in the northern of the Ordos Basin is hosted in the lower sub-member，lower member of Zhiluo Formation，with an average uranium grade of 0.057 1% and an average uranium mass per square meter of 6.69 kg/m2，but its permeability coefficient is only 0.065 m/d，which is a typical low-permeable sandstone uranium deposit. For this deposit，the well Z5，which has poor injection capacity，is selected to carry out the high energy gas fracturing experiments. The uranium deposit aquifer of the well is located at 619~639 m，and the depth of the propellant is placed at 632.5~637.4 m，626.6~631.6 m，620.6~625.6 m. The amount of the propellant is 40 kg for each time. At the same time of fracturing，microseismic monitoring is carried out around well Z5. There are 59，61 and 49 events generated by the fracturing of three times，and the event profiles show that the fractures formed in the reservoir are trending at 46.8°NW，31.0°NW and 72.3°N，respectively. After fracturing，the injection volume of well Z5 is significantly improved，with an increasement of 126.34%. The high energy gas fracturing can improve the permeability of the near-well area. It is easy to implement and the cost is low.
