Mechanisms behind consolidation-induced water release from effective impermeable soil layers and mine water inflow prediction in coal mining

Meitian dizhi yu kantan
BackgroundIn the Yushen mining area, coal mining is gradually shifting toward areas with thick soil layers. This leads to continuous water release from the saturated soils above the hydraulically conductive fracture zones, thereby significantly ...

Analysis of the influence of different rock (soil) bodies on the failure characteristics of overlying rock in Yushen mining area

Abstract In order to analyze the influence of different rock ( soil ) bodies on the failure mode of overburden rock in Yushen mining area, three types of overburden rock structures, including red soil-weathered bedrock-normal bedrock, weathered bedrock-normal bedrock and normal bedrock, were selected in the range of mining-induced cracks.
