Computer Numerical Simulation of Sluice Structure on Deep Overburden Foundation [PDF]
This paper adopts the space combination finite element method to calculate the whole displacement and stress of chamber structure and foundation, calculates the overall stability against sliding and anti-floating stability safety coefficient of the lock chamber structure via the rigid body limit equilibrium method, and simulates the excavation and ...

Coevolution mechanism and branch of pillar‐overburden fissures in shallow coal seam mining
The large‐scale mining of coal resources promotes the formation of section coal pillar groups between working faces. The overlying strata are supported by coal pillars, which leads to the formation of a unique fracture‐bearing structure in the key ...

STUDY OF OVERBURDEN TUFF ROCKS AND DEVELOPMENT ON ITS BASIS OF LIGHTWEIGHT STRUCTURAL CONCRETE [PDF]
Introduction. The work presents the research results on the development of technology for lightweight structural concrete based on overburden tuff rocks. To develop the technology of lightweight structural concrete, overburden tuff rock (Almaty region of the Republic of Kazakhstan) is used, which is formed during the extraction of volcanic tuff for ...

Analysis of Overburden Structure and Pressure‐Relief Effect of Hard Roof Blasting and Cutting [PDF]
When studying the pressure‐relief effect of hard roof blasting and cutting, the roof‐cutting position and angle obviously affect the stability of the rock surrounding the gob‐side entry (GSE). In this paper, control of the large deformation of rock surrounding the GSE is evaluated on the basis of the overlying structure and pressure‐relief principle ...

Overburden-Induced Flattening Structure in the Himalaya: Mechanism and Implication
Small-scale structures in fold-thrust belt are mainly formed in response to the emplacement of thrust sheets. However, some small-scale structures may not be developed directly in response to the emplacement of thrust sheets, but might be genetically tied with the orogenic process.
