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.

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 ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 The hydrogeochemical characteristics of coalbed‐produced water can provide insights into the sources of ions and water, the groundwater environments, hydrodynamic conditions, and water‐rock interactions of depositional basins. To study the water‐rock reaction process and reveal whether there is a microbial activity in the groundwater, a case of the ...

Experimental Study on Flow Characteristics of Aeolian Sand in Fractures
Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 It is one of the important safety problems in the process of mining shallow coal seams in western China that the rock mass affected by mining stress breaks and forms a penetrating fracture, leading to a sand burst in the working face. The self‐developed test system is used to carry out the experimental study on the flow characteristics of Aeolian sand ...
