[1] Ground-penetrating radar (GPR) helps to constrain the origin of relict and largely buried fluvial channels in the Bir Kiseiba region of southern Egypt. Our results indicate that the trunk channel to a tributary system identified in Shuttle Imaging Radar data is incised 10–12 m into bedrock, was southwest draining in its final configuration and laterally migrating toward the northwest, and a...

For the thick alluvium and thin bedrock coal seam mining in East China, it is easy to produce water by pressing frame. Taking engineering geological conditions of 1611 (3) working face Zhangji Coal Mine Huainan Mining Group as research background, breaking law with was studied using a similar material physical simulation experiment theoretical analysis. It revealed that under load transfer loos...
