49+ min ago   (543+ words) In saline strata, lubricating slurry for pipe jacking deteriorates due to salt ion intrusion, causing stratum instability and increased frictional resistance, which pose major risks in underground construction in coastal and inland saline areas. This study investigates the evolution of…...

17+ hour, 3+ min ago   (102+ words) In this study, to address the overlying strata control issue for the isolated working face of a super-thick coal seam confined by surrounding goafs and open-pit boundaries, we focus on mining via upward slicing strip paste filling in a Ningxia…...

18+ hour, 59+ min ago   (670+ words) To address the challenge of surrounding rock control in deep gob-side entry driving, the return airway of the 20203 working face of the Dahaize Coal Mine was taken as the engineering background. The stress, deformation and plastic zone evolution characteristics of…...

20+ hour, 12+ min ago   (435+ words) To overcome the limited dust control efficiency and backward dust diffusion tendency in fully mechanized excavation faces, this study pioneeringly proposes a wind-splitting dust control method based on a mechanical iris structure. This method actively splits and precisely allocates the…...

1+ day, 19+ hour ago   (428+ words) The discharge of metal-rich mining effluents and waste into marine environments represents a significant environmental challenge, with impacts extending from coastal to deep-sea ecosystems. This study presents a scoping review conducted in accordance with PRISMA-ScR guidelines to identify, classify, and…...

2+ day, 21+ hour ago   (397+ words) Conveyor belt systems are commonly treated as industrial equipment, although their operational value, degradation, risk, and renewal potential are distributed along the route and evolve through identifiable belt sections, splices, inspections, repairs, inserts, and refurbishment cycles. This article redefines conveyor…...

3+ day, 17+ hour ago   (424+ words) Acoustic emission (AE) monitoring is widely used to characterize coal failure, but specimens with different burst tendencies cannot be distinguished reliably using a single count, energy, b-value, or fractal indicator. This study reanalyzed archived Vallen AE data from uniaxial-compression tests…...

4+ day, 23+ hour ago   (494+ words) Deep longwall mining under large dip and advance inclinations can induce strongly asymmetric roof deformation and nonuniform load transfer, complicating the assessment of hydraulic support loading. Taking the 2902 working face of Chensilou Coal Mine as an engineering case, this study…...

5+ day, 22+ hour ago   (504+ words) This study presents an integrated multidisciplinary framework for evaluating the reuse of abandoned underground mining infrastructure in Bosnia and Herzegovina as sustainable underground energy storage systems that support the energy transition and decarbonization. The research focuses on the Central Bosnia…...

6+ day, 23+ hour ago   (399+ words) The objective of the research presented in this paper was to develop methods for simulating the operating conditions of traction power supply systems (TPSSs) equipped with asynchronous generators (ASGs), which may be driven by wind or hydraulic turbines as prime…...
