Simulation of water resource loss in short-distance coal seams disturbed by repeated mining
Physical simulations and field measurements were performed to study the movement of overlying strata and water conductive fractures (WCF) under conditions of repeated mining in short-distance coalExpand
Tribological behavior of poly (phenyl p-hydroxybenzoate)/polytetrafluoroethylene composites filled with hexagonal boron nitride under dry sliding condition
Abstract The sliding friction and wear behavior of polytetrafluoroethylene (PTFE) composites filled with poly (phenyl p-hydroxybenzoate) (PHBA) and hexagonal boron nitride (h-BN) was investigatedExpand
Concurrent Mining During Construction and Water-Filling of a Goaf Groundwater Reservoir in a Coal Mine
Coal mining has aggravated water scarcity in the arid areas of northwestern China. Concurrent aquifer drainage, mining, and water storage is proposed, using a goaf groundwater reservoir (GGWR) toExpand
Non-destructive inspection on anchorage defect of hollow grouted rock bolt using wavelet transform analysis
TLDR
The test results show that the free length of hollow grouted rock bolt could be accurately detected through the analysis of the stress wave signal by using the low-pass filter in the wavelet toolbox. Expand
Tribological behaviors of polytetrafluoroethylene composites under dry sliding and seawater lubrication
The composites of polytetrafluoroethylene (PTFE) filled with expanded graphite (EG), poly(p-oxybenzoyl) (POB), and ba- salt fiber (BF) were prepared by heating compression and sintering molding. TheExpand
An Elastoplastic Softening Damage Model for Hydraulic Fracturing in Soft Coal Seams
In order to improve the permeability of soft coal seams with low intensity and permeability by hydraulic fracturing, an elastoplastic softening damage model of soft coal seams has been established,Expand

  • 15 June 2020
The increasing demand for energy makes it difficult to replace fossil fuels with low-carbon energy sources in the short term, and the large amount of CO2 emitted by fossil fuel combustion increasesExpand
Influence of freeze–thaw cycles on mechanical responses of cemented paste tailings in surface storage
ABSTRACT Surface cemented paste tailings disposal (SPD) has become a useful practice in many mines around the world. The method is a sustainable tailings management that returns tailings to fill theExpand
Coupled Thermo-Hydro-Mechanical-Chemical Modeling of Permeability Evolution in a CO2-Circulated Geothermal Reservoir
The meager availability of water as a heat transfer fluid is sometimes an impediment to enhanced geothermal system (EGS) development in semi-arid regions. One potential solution is in substitutingExpand
