Abstract The Junggar coal basin, with enormous coal reserves, is one of the largest coal basins in Xinjiang Province, Northwest China. According to the exploration data, there is one to dozens of workable coal seams developed in the Xishanyao Formation of Middle Jurassic across the whole basin, with the maximum accumulated coal thickness of over 100 ...

The risk assessment of roof water inrush is of great significance for sustainable development of mine and ecological environment. Taking the Jurassic coalfield in northwest China as an engineering background, we firstly selected nine indexes influencing roof water inrush based on three essential conditions with the water source, the water inrush ...

Jurassic weathered bedrock is widely distributed in the Jurassic coalfield of Northern Shaanxi Province. Its fracture network is connected with each other well, which provides a good space foundation for groundwater storage. It makes bedrock weathered zone become one of the important aquifers that endanger coal mine safe production.

Abstract A large amount of thin-film dawsonite has developed in coal cleats and also in fractures within the roof sandstone in Jurassic CO 2 -rich coal measure strata of the Yaojie coalfield, Minhe Basin, China. The CO 2 in these strata has been in a supercritical state since natural emplacement.
