Numerical Simulation Research on Deep Soft Rock Roadway

Applied Mechanics and Materials, 2012
The soft rock roadway support is one of difficult problems in the mineral engineering. For making the stress and strains of support system to be effective forecasted in the process of roadway support. The Adina finite element software is used to do numerical simulation about the strains of the supports system in the process of the Hama mountain roadway,

Floor Heave Controlling Technology of Deep Soft Rock Roadway

Applied Mechanics and Materials, 2012
The floor heave is one of soft rock roadway distortion. Based on soft rock supporting theory and engineering practice, the program bolt-mesh-anchors and floor corner, bolts coupling support to control floor heave of the soft rock roadway is proposed. Numerical simulation results show that bolt-anchors can mobilize the strength of the deep adjacent rock,

Comprehensive study on identification of water inrush sources from deep mining roadway

Environmental Science and Pollution Research, 2021
To accurately identify the location of the water inrush sources, correlation analysis and factor analysis were used to discuss the similarity of hydrochemical control mechanism of different aquifers and inrush water. On this basis, Fisher and BP neural network are used to judge the probability of inrush water.
