Sedimentology and kinematics of a large, retrogressive growth-fault system in Upper Carboniferous deltaic sediments, western Ireland [PDF]
, 2004 Growth faulting is a common feature of many deltaic environments and is vital in determining local sediment dispersal and accumulation, and hence in controlling the resultant sedimentary facies distribution and architecture.

Mechanism and Evolution Control of Wide Coal Pillar Bursts in Multithick Key Strata
Shock and Vibration, 2021 Coal mine pillar burst frequently occurs in Western China, which seriously restricts safe production. This paper takes the 35 m coal pillar of the 3102 working face of MKQ coal mine as the engineering background. The mechanism and evolution control of pillar bursts in multithick key strata are studied using field investigation, theoretical analysis ...

Study on Deformation and Failure Law and Instability Mechanism of Slope in Open-underground Mining
Meikuang Anquan, 2020 Based on the existing key strata theory, the concept of “the key strata” which controls the open-underground mining slope stability was proposed, taking open-underground mining in Pingshuo Mining Area as an example, the deformation and failure regularity
