Floor Heave Mechanism of Gob-Side Entry Retaining with Fully-Mechanized Backfilling Mining
Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue backfilling mining affects the transportation and ventilation safety of the mine. A theoretical mechanical model for the floor of gob-backfilled GER was established. The effects of the mechanical properties of floor strata, the granular compaction of backfilling area (BFA), the vertical support of roadside suppor...

متن کاملDeformation mechanism and optimum design for large cross-sectional longwall installation roadway under compound roof
Both the deformation characters and the failure mode of the large cross-sectional longwall installation roadway under compound roof are becoming an emergent issue than ever before due to the rapid development of modern mining equipment. Various engineering applications have revealed that the insufficient design and inappropriate support technology are the main reasons for the fatal accidents as...
متن کاملIterative Optimization Method of Gob-volterra Filters
An iterative method is proposed to optimize the Volterra kernels expansions on Generalized Orthonormal Bases (GOB). Each kernel is expanded on an independent GOB. The expansion coefficients, also called Fourier coefficients, are estimated in using an orthogonal formulation of the Least Squares (LS) algorithm. The proposed method allows optimization of both the Fourier coefficients and the GOBs ...
متن کامل3D roof model generation and analysis supporting solar system positioning
Given the growing needs of renewable energy in urban areas, identifying suitable installation locations for solar systems is increasingly important. Existing energetic cadastres have often a limited level of detail in the analysed geometry, which needs to be rapidly updated following any changes in the buildings. The required 3D data can be generated by photogrammetry techniques and Structure-f...
