Fatigue crack paths under the influence of changes in stiffness by G. Kullmer, B. Schramm, H. A. Richard

“…Regions with differing stiffness also arise from ribs, grooves or boreholes. Since secure findings on the propagation behaviour of fatigue cracks are essential for the evaluation of the safety of components and structures, the growth of cracks near changes in stiffness has to be considered, too. …”

Le permafrost de montagne et les processus géomorphologiques associés : évolutions récentes dans les Alpes françaises by Xavier Bodin, Philippe Schoeneich, Philip Deline, Ludovic Ravanel, Florence Magnin, Jean-Michel Krysiecki, Thomas Echelard

“…Since the beginning of these measurements at depth in 2010, a trend of increasing temperature has been discernible, as found in other alpine boreholes. As clearly shown by the surface measurements conducted since 2003, the thermal regime is influenced by snow, particularly in surficial deposits and to a much lesser extent in rock walls. …”

Monitoring Excavation-Induced Deformation of a Secant Pile Wall Using Distributed Fiber Optic Sensors by Chengyu Hong, Chengkai Xu, Weibin Chen, Jianwei Liu, Junkun Tan

“…During excavation, the temperature changes were minimal, but the excavation depth significantly influenced the strain distribution, with continuous compressive deformation observed in two monitored boreholes. Two analytical methods, the numerical integration method (NIM) and the finite difference method (FDM), were used to calculate the lateral pile displacement based on the monitored strain data. …”

Quantitative Evaluation for the Threat Degree of a Thermal Reservoir to Deep Coal Mining by Yun Chen, Xinyi Wang, Yanqi Zhao, Haolin Shi, Xiaoman Liu, Zhigang Niu

“…The evaluation results show that the threat degree of the roof in the eastern region is generally greater than that in the western region and that the closer it is to the coal seam outcrop line, the higher the threat degree is; near the boreholes, in the areas Qs1,Qs5, Qs8, Sx1, Tk5, Zc4, and Zc7, which are close to the hidden outcrop line of the coal seam, the classification characteristic value of the threat degree is greater than 3.5, which is in the high-threat zone for disasters caused by roof thermal storage aquifers during coal seam mining. …”

Coal Seam Gas Extraction by Integrated Drillings and Punchings from the Floor Roadway considering Hydraulic-Mechanical Coupling Effect by Chaojun Fan, Haiou Wen, Sheng Li, Gang Bai, Lijun Zhou

“…Results show that gas extraction can reduce coal seam gas pressure and slow down the rate of gas release, and the established hydraulic-mechanical coupling model can accurately reveal the law of gas extraction by drilling and punching boreholes. After adopting the gas extraction technology of drilling and hydraulic punching from the floor roadway, the remaining gas pressure and gas content are reduced to lower than 0.5 MPa and 5.68 m3/t, respectively. …”
