Construction of 3D geological and in-situ stress model of coal roof based on Petrel

open access: yesMeikuang Anquan, 2023
The simulation of the initial stress field of coal rock generally generalizes the coal seam, roof and floor and overlying rock layer into isotropic plates, and the stress field simulation of the entire wellfield scale has certain limitations if this ...

Bursting Liability Criteria of Coal Mass Based on Energy Storage and Release Characteristics. [PDF]

open access: yesACS Omega, 2023
The bursting liability of coal, referring to the characteristic of coal to accumulate strain energy and produce impact damage, is an important factor influencing the occurrence and extent of rock burst disasters in coal mines. Two indicators-the elastic strain energy storage coefficient and energy release coefficient-are proposed based on the energy ...

Crack Evolution Behaviors and Bursting Liability of Sandstone with Different Sizes: An Experimental Study. [PDF]

open access: yesACS Omega, 2023
The size ranges of ore pillars play important roles in preventing the occurrences of rock burst phenomena. Due to the lack of research on the relationship between crack evolution behaviors and bursting liability of rocks with different sizes, uniaxial compression tests on sandstone with different height-to-diameter ratios (H/D) were conducted.

Legal Liability for Bursting Reservoirs: The Historical Context of "Rylands v. Fletcher"

open access: yesThe Journal of Legal Studies, 1984
THERE now exists a considerable literature concerned to explain the development of tort law in the nineteenth century.' Some writers have concentrated on the procedural and doctrinal aspects of the process as a prerequisite to any secure progress with wider questions.2 Others have seen in the subject an opportunity to develop more general theories of ...

The Floodgates of Strict Liability: Bursting Reservoirs and the Adoption of Fletcher v. Rylands in the Gilded Age

open access: yesThe Yale Law Journal, 2000
Part I presents an overview of Rylands v. Fletcher and then discusses the phases of the American response: the initial acceptance; the Northeastern rejections in the 1870s, which have been the basis for the erroneous scholarly conclusions; and the ...

Measurement and Classification Criteria of Strength Decrease Rate and Brittleness Indicator Index for Rockburst Proneness Evaluation of Hard Rocks. [PDF]

open access: yesMaterials (Basel), 2023
Rockburst is one of the common geological hazards. It is of great significance to study the evaluation indexes and classification criteria of the bursting liability of hard rocks, which is important for the prediction and prevention of rockbursts in hard

A new burst evaluation index of coal–rock combination specimen considering rebound and damage effects of rock

open access: yesGeomatics, Natural Hazards & Risk, 2020
Obtaining the bursting liability is essential for rock burst mitigation. To reasonably evaluate the bursting liability of coal in deep coal mining, a new modified bursting energy index considering rebound and damage effects of rock is proposed.
