Karst, GIS and geological hazard planning and management in Great Britain [PDF]

, 2010
The British Geological Survey (BGS) database of karst features for the United Kingdom include dolines, cave entrances, stream sinks, resurgences and building damage; data for approximately half of the country has so far been gathered.

Estimation of surface subsidence during tunneling

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The limitations of the traditional methods of assessing the surface subsidence and the state of structures and natural objects in mining operations are shown. An innovative approach to predicting the surface subsidence during tunneling is proposed.

Research on Strip Filling Surface Subsidence Rule [PDF]

Proceedings of the Taishan Academic Forum - Project on Mine Disaster Prevention and Control, 2014
For recycling the remaining coal pillars resources in strip mining, a repeated mining method of using the strip filling replacement of strip coal pillar is proposed, a technical principle of strip filling controlling surface subsidence is illustrated, and the main filling factors which influence the surface subsidence rule are analyzed, FLAC3D is used ...

On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

Advanced Engineering Materials, EarlyView.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

Advanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

A Novel Surface Subsidence Prediction Model Based on Stochastic Medium Theory for Inclined Coal Seam Mining

Advances in Civil Engineering, 2023
Most coal resources are deposited in the form of inclined coal seams, and surface subsidence basin morphology induced by the mining of inclined coal seams is frequently skewed. The probability integral method with symmetrical distribution characteristics

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

Advanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Numerical modeling of two-dimensional temperature dynamics across ice-wedge polygons [PDF]

, 2017
Thesis (M.S.) University of Alaska Fairbanks, 2017The ice wedges on the North Slope of Alaska have been forming for many millennia, when the ground cracked and the cracks were filled with snowmelt water.
