Publisher: American Society of Civil Engineers
Abstract: A rock burst can cause a serious disaster. For the mitigation of rock burst-induced disaster, the possibility assessment of a rock burst for an underground excavation is a key undertaking and also a great challenge because ...
Physical Experiment and Numerical Simulation Study on Balanced Mining Based on the 110 Mining Method in Shallow-Buried Thin Bedrock with a Thick Weathered Layer
Publisher: American Society of Civil Engineers
Abstract: Abstract Surface subsidence and ecological destruction caused by underground coal mining have
become hot topics in mining research. To reduce the negative externalities of mining
activities, China has proposed a balanced ...
Spatiotemporal Evolution Process and Mechanism of the Rainfall-Landslide-Tunnel Failure Disaster Chain: A Case Study in Fengjie County, Chongqing, China, July 2, 2016
Publisher: American Society of Civil Engineers
Abstract: AbstractUnder rainfall conditions, the loose accumulation layer in the tunnel entrance area
is prone to landslide hazards. This study established a rainfall-landslide-tunnel
failure disaster chain (RLTDC) using the Yangjiawan ...
Evaluation of the Supporting Effectiveness of Negative Poisson’s Ratio Anchor Cables in Antidip Slope Excavation and Seismic Response
Publisher: American Society of Civil Engineers
Abstract: Abstract The seismic instability of antidip rock slopes represents a critical issue in the
prevention and control of geological disasters. The seismic stability of antidip rock
slopes, reinforced using negative Poisson’s ...
Rock-Cutting Mechanics Model and Its Application Based on Slip-Line Theory
Publisher: American Society of Civil Engineers
Abstract: Rock mechanics parameters for underground engineering cannot be rapidly or comprehensively tested on site; thus, this article presents a method for determining rock mechanics parameters using drilling parameters obtained ...
Enhancing Directional Rock Fracturing with Instantaneous Expanding Slit Former Technology
Publisher: American Society of Civil Engineers
Abstract: Abstract Traditional rock blasting with explosives is marked by extensive pulverization, chaotic
fracturing, suboptimal shaping outcomes, and stringent controls. As a result, a nonexplosive
technology for directional rock ...
