摘要:AbstractDouble-wheel trench cutters display reduced efficiency while cutting through hard or extremely hard rock strata, leading to significant wear on their picks. A high-pressure water jet-pick combined rock-breaking method (HPC) for double-wheel trench cutters is proposed, addressing the challenges of low efficiency and high pick wear when cutting hard rock strata. The HPC mode integrates hi...

关键词:Form and load transfer aspects of foundation systems Casebased implementation adaptation for buildings
摘要:AbstractConventionally, foundations have been classified as shallow or deep in routine civil engineering practice. However, due to recent developments, two other approaches, semi-deep and ground modification foundations, are now available, complicating foundation categorization. Accordingly, a new concept for foundation categorization is introduced in this paper based on insights into the theor...

关键词:Slit tube responses and rock fracture characteristics in slit charge blasting under high situ stress
摘要:AbstractDeep mining of natural resources, like coal, is increasingly utilizing directional blasting technology with slit charge for rock blasting at greater depths. This study, based on numerical simulation methods, analyzes the dynamic behavior of slit charge blasting in three aspects: slit tube dynamic response, hoop stress evolution, and crack propagation. According to research findings, the...
