Nonlinear seepage erosion model of water inrush considering particle size distribution of karst collapse column and its engineering applications [PDF]

open access: yesScientific Reports, 2022
Water inrush through karst collapse column is one of the great disasters which threaten coal mine safety production. The particle size distribution of karst collapse column is one of its most basic physical properties, which has a strong correlation with

A non-linear flow model for the flow behavior of water inrush induced by the karst collapse column. [PDF]

open access: yesRSC Adv, 2018
Water inrush induced by the karst collapse column (KCC) is a great threat to coal mine safety. In this study, a non-linear flow model that couples three flow types is built based on flow transition from laminar flow in the aquifer to turbulent flow in ...

Research on Collapse Risk Assessment of Karst Tunnels Based on BN Self-Learning

open access: yesBuildings
The high risk of collapse is a key issue affecting the construction safety of karst tunnels. A risk assessment method for karst tunnel collapse based on data-driven Bayesian Network (BN) self-learning is proposed in this study.

Study on early-warning System of Karst Tunnel Collapse [PDF]

open access: yesE3S Web of Conferences, 2020
During the construction of karst Tunnel, tunnel collapse often occurs. The establishment of early-warning system of tunnel collapse can effectively ensure the construction safety, but the research is insufficient.
