Dynamic cracking properties and generating conditions of coal under rapid gas release
Deep Underground Science and Engineering, EarlyView.Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

Deep Underground Science and Engineering, EarlyView.The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Deep Underground Science and Engineering, EarlyView.High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
