The Spatio‐Temporal Evolution of Overlying Rock Structure and Mine Pressure Behavior in a Short‐Distance Coal Seam Face

Geofluids, Volume 2022, Issue 1, 2022., 2022
This research is aimed at exploring the evolution of overlying strata structure and the ground pressure in the working face mining of close‐distance coal seams. By taking the Xiashijie Coal Mine as an example, the direct relationship between the rotation angle of key blocks of overlying strata and the subsidence of key blocks and the length of rock ...

Study on Layered‐Backfill‐Based Water Protection Technology of Thick Coal Seam in the Ecologically Fragile Mining Area in Western China

Geofluids, Volume 2022, Issue 1, 2022., 2022
The mining areas in Western China are characterized by water shortage and ecological fragility, and the coal resources in these areas are extracted in a large‐scale and highly intensive manner, which is highly likely to induce ecological problems, such as soil erosion and grassland degradation.

On a Possible Mechanism of Hydrostatic Pressure on Mineshaft Linings in Western China

Geofluids, Volume 2022, Issue 1, 2022., 2022
Reasonable determination of the water pressure on the shaft linings is the key to the optimization design of the vertical shaft of mining. The traditional water pressure calculation model is not suitable for the stratum conditions in western China. A new shaft‐surrounding rock seepage model is proposed based on the coordinated seepage conditions of ...

Mechanism and Control of Rockburst Induced by Draining Spatial Islands and Squaring

Geofluids, Volume 2022, Issue 1, 2022., 2022
A small‐pillar gob‐side roadway showed rockburst appearance during the mining of a gob‐side working face located in the Shaanxi‐Inner Mongolia mining area. This study examines the 2202 gob‐side working face of a coal mine in Inner Mongolia as a case study.

Head‐On Dynamic Manifestations in the Roadway Driving with Small Coal Pillar under the Influence of Roof Drainage: A Case Study from Uxin Banner

Geofluids, Volume 2022, Issue 1, 2022., 2022
In the Uxin Banner area of the Inner Mongolia Autonomous Region, mines that have experienced rock bursts have all been affected by the presence of confined water in the roof strata. Strong mine pressure appears in the working face with about 30 m wide coal pillar in this area, and the research and practice of prevention and control of rock burst by ...

Water Richness Zoning and Evaluation of the Coal Seam Roof Aquifer Based on AHP and Multisource Geological Information Fusion

Geofluids, Volume 2021, Issue 1, 2021., 2021
Roof water disaster is one of the most serious disasters in the process of coal mine safety mining in China. The thickness of modern comprehensive mechanized coal mining is large, which has a great impact on the roof aquifer, and the threat degree of water disaster is also increasing.

Determination of Mining‐Induced Changes in Hydrogeological Parameters of Overburden Aquifer in a Coalfield, Northwest China: Approaches Using the Water Level Response to Earth Tides

Geofluids, Volume 2021, Issue 1, 2021., 2021
The determination of changes in hydrogeological properties (e.g., permeability and specific storage) of aquifers disturbed by mining activity is significant to groundwater resource and ecological environment protection in coal mine areas. However, such parameters are difficult to continuously measure in situ using conventional hydrogeological methods ...
