Fluid samples were collected from the Navajo Sandstone at formation pressures using a positive displacement wireline sampler and fluid CO2 content and pH were measured at surface

Evaluation of the rockburst proneness of red sandstone

 · The PESI of red sandstone specimens with boreholes decreased by 23.2 –70.2 compared with that of intact specimens i.e. DPR can effectively reduce the rockburst proneness of rocks. Furthermore the effects of the number and arrangement of boreholes on rockburst proneness were evaluated. The PESI decreased as the number of boreholes increased.

The drilling diameter of red sandstone was 100 mm and 60 mm respectively. The results showed that the energy consumption of EPB was about J/cm³ without slag discharge system.

Weight analysis and experimental study on influencing

The drilling speed in the granite was 0.4 times of that in the red sandstone when EPB was used to break through the rock. While mechanical drilling was used the drilling speed in the red sandstone was 0.07–0.08 times of that in the granite (Ushakov et al. 2019).
