Stress superposition characteristics and roof structure control of recovery room in close distance coal seam
Published 2025-06-01“…The results show that: By establishing a mechanical model of the roof of the recovery room during the final mining period, it is determined that under the geological conditions of the mine, the support resistance P1≥3.05 MPa in the recovery room can ensure the stability of the surrounding rock of the recovery room after the working face and recovery room are connected; Using empirical formulas optimized by multiple linear and nonlinear regression analysis, it is estimated that the depth of failure of the upper coal seam working face floor is greater than 8.41 m and less than the interlayer spacing of 13.3 m; Using the UDEC numerical calculation model, the evolution law of cracks on the roof of the recovery room was inverted, and reinforcement measures were taken 10 m in advance for the roof of the recovery room under the goaf, and 15 m in advance for the roof of the recovery room under the coal pillar; Propose a comprehensive stability control technology for the combined active and passive support of anchor cables and individual pillars in the recovery room, as well as the advanced pre cracking of the surrounding rock in the inner roof of the coal pillar lower channel, and apply it to different stress affected areas of the recovery room. …”

Development and validation of mPCR-CEFA for detecting multiple deletion and non-deletion thalassemia genotypes
Published 2025-07-01“…The performance of mPCR-CEFA was validated against conventional methods, including Gap-PCR and PCR-RDB.ResultsThe α1/α2 and Y1/Y2 peak ratios exhibited stable and reproducible values, allowing for precise genotyping of thalassemia events involving homologous recombination, such as -α3.7, -α4.2, αααanti3.7, αααanti4.2 and HKαα. Mutation peaks in different fluorescent channels also facilitated the differentiation of various genotypes, including deletion and non-deletion types. …”
