Study on Influencing Factors and Prediction of Tunnel Floor Heave in Gently Inclined Thin-Layered Rock Mass

In recent years, the construction of new railway tunnels worldwide has become increasingly challenging due to larger cross-sections, deeper burial depths, higher in situ stress, and more complex geological conditions.

Experimental Study on Anti-Shear Properties of Floor Heave Control Anchor of Deep Soft Rock

, 2011
With the increase of Chinese mining depth, the deformation of deep soft rock is an increasingly serious problem, such as floor heave. The shear experiments of the different types of anchor were carried out. The results show that the anti-shear properties

Floor Heave Control in Gob-Side Entry Retaining by Pillarless Coal Mining with Anti-Shear Pile Technology

The severe floor heave in gob-side entry retaining is the major restriction factor of the wide application of pillarless mining thin coal seams. Reinforcement and stress-relief floor heave control methods are the most promising.

Set-Point Algorithms for Active Heave Compensation of Towed Bodies

, 2016
Active heave compensation is a technique used in marine applications to attenuate undesirable wave motions between a load and its host vessel. Motion attenuation is often achieved by reeling in or reeling out a cable tethering the load to the host vessel

Rock Mass Bolting in Coal Mine Workings for Floor Heave Control

This article addresses the problem of floor heave in preparatory mine workings of the Karaganda Coal Basin and proposes technological solutions based on rock mass anchoring systems. Long-term field observations, supported by analytical interpretation and
