Paleogeography and coal accumulation model of the Middle Jurassic Xishanyao Formation in western Dananhu Coalfield of Turpan-Hami Basin

Meitan xuebao
The Dananhu Coalfield in the southeastern part of the Turpan-Hami Basin contains abundant coal resources, but the coals in this area have multiple layers and vary greatly in thickness, resulting in increased difficulty in coal exploration.

Construction and application of a model for drainage via directional boreholes against water hazards in deep vertical shafts

Meitian dizhi yu kantan
BackgroundVertical shafts are typically employed in the deep mining areas of Jurassic coalfields in western China. However, the direct exposure of extremely thick Cretaceous aquifers frequently leads to significant water inflow in shafts.

Research on mechanism and risk assessment of water and sand outburst in weakly cemented rock layers of Jurassic coalfields

Meikuang Anquan
Due to the relatively late coal-forming period in the Jurassic coalfields in western China, the rock characteristics often exhibit poor cementation, low strength, and easy softening and collapse in contact with water, which leads to the occurrence of water and sand outburst events in weakly cemented rock layers during mining. Therefore, identifying the
