Experimental Study on Overburden Deformation Evolution under Mining Effect Based on Fiber Bragg Grating Sensing Technology

Journal of Sensors, Volume 2020, Issue 1, 2020., 2020
In order to study the regularity of overburden deformation and mining pressure changes in the stope. Take the geological conditions of Hanglaiwan coal mine in Yushen mining area as the background, a 3000 mm × 1340 mm × 200 mm physical similar material model was established in laboratory.

Numerical Study of Damage to Rock Surrounding an Underground Coal Roadway Excavation

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
In coal mines, underground roadways are required to transport coal and personnel. Such tunnels can become unstable and hazardous. This study simulates deformation and damage in the rock surrounding a shallow coal seam roadway using particle flow code. A numerical model of particle flow in the surrounding rock was constructed based on field survey and ...

Study on synergistic water-resisting stability of upper and lower soil layers and bedrock layer in shallow coal seam group [PDF]

, 2023
The roof water inrush of shallow buried coal seam is caused by the water flowing fractured zone through the aquifuge. With the downward mining of coal seam group, the mechanism of synergistic water isolation between soil layer and bedrock layer needs to ...

Mechanism of Dynamic Failure in Roadways with Thick and Competent Roof Strata: A Case Study

Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019
Rock and coal dynamic failures have a higher chance to occur when thick and competent roof strata are presented, which can build up a high level of energy. This paper studied the fracturing characteristics of the competent roof strata during longwall face retreat and their effects on roadways’ stability to gain an improved understanding of the rock ...
