Ali JENABIDEHKORDI

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 2,   Pages 273-287 doi: 10.1007/s11709-018-0459-5

Abstract: overview of the most popular state-of-the-art computational methods available for modelling fracture in rockmethods which can be found elsewhere but particularly address their potential in modelling fracture in rockFurthermore, we also address ‘general’ difficulties that may arise for simulating fracture in rock andfractured rock.

Experimental study on slurry-induced fracturing during shield tunneling

Teng WANG, Dajun YUAN, Dalong JIN, Xinggao LI

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 2,   Pages 333-345 doi: 10.1007/s11709-021-0718-8

Abstract: Hydraulic fracturing may occur and cause a significant decrease in the support pressure if the slurrypressure exceeds the threshold of the soil or rock material, resulting in a serious face collapse accidentof related influencing factors on the hydraulic fracturing pressure and fracture pattern.In this study, a hydraulic fracturing apparatus was developed to test the slurry-induced fracturing ofThe unconfined compressive strength of soil can reflect its ability to resist fracturing failure.

Horizontal effects in fracturing operation of coal bed methane in Qinshui,Shanxi Province

Li Mengxi,Zhang Cong

Strategic Study of CAE 2012, Volume 14, Issue 4,   Pages 16-19

Abstract:

This paper describes horizontal effects of CBM (coal bed methane)fracturingfractures have adverse effects, including reduced production flow rate, depletion, and watering during fracturingThis discovery shows that the horizontal compression of fracturing could have adverse impact on productionof adjacent wells, and fracturing designer should be aware of it.
