Analytical study of groundwater flow field and inrush flux distribution for deeply-buried circular arched tunnels by Yunbo WEI, Jinguo WANG, Zhou CHEN, Kexun ZHENG

“…The results reveal that the groundwater flow field near the tunnel is significantly influenced by the tunnel shape, while its influence on the groundwater flow field further away from the tunnel can be approximated as that of a tunnel with a circular cross-section. The maximum flow velocity around the circular arched tunnel occurs near the inflection points (i.e., the corners of the tunnel bottom), while the minimum flow velocity is located at the center of the tunnel floor. …”

Study on the Deformation Mechanism of the Bottom Plate along the Empty Lane of Deep Mining and the Control Technology of the Bottom Drum by Dongdong Pang, Xingang Niu, Kai He, Chuanming Li, Dawei Pang, Tao Hu, Zhongqi Chen, Xiaolong Luo

“…Aiming at the problem of the deformation of the roadway floor plate during the laneway during the retention period, the mechanical model of the roadway floor is established, and the deformation characteristics of the roadway floor and the change law of the bottom drum are studied and analyzed through theoretical calculation and calculus simulation, revealing the instability mechanism of the surrounding rock of the roadway under the stress disturbance environment, and when not affected by the adoption, the roadway forms a certain stress concentration area within the effective range of support. …”
