Five‐year tomographic and clinical evaluation of the socket shield technique: Case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The socket shield technique, one modality of partial extraction therapy, aims to preserve periodontal tissues and maintain the buccal alveolar bone volume following immediate implant placement or in prosthetic pontic sites, by the strategic maintenance of a tooth root fragment.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Superstructure Behavior of a Stub-Type Integral Abutment Bridge

Journal of Bridge Engineering, 2014
Records show that research leading to the successful introduction of integral-type structures such as continuous beams and frames actually began in the 1930s. Simple stub-type abutments have been found to perform well and are recommended for widespread use. The purpose of this analysis was to consider the behavior of the superstructure and substructure/

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

Deep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Monitoring of a bridge with integral abutments

, 2009
Preliminary results obtained from short term test-loading are used to illustrate possibilities of FEM used to calibrate complex interaction characteristics between a pile and soil in a bridge with integral abutments. The measurements are obtained during the winter season on the bridge over Leduån, in Northern Sweden.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...
