Large-scale mining operations in western China would accelerate the fragility and degradation to arid ecological environments. Remotely sensed monitoring assessing of effects long term change could provide sound understanding guide mine restoration local ecosystem sustainability. This study's primary goal is develop an mined land status (AMLS) index based on remote sensing data assess areas land. Furthermore, performance AMLS was contrasted with that (RSEI) surface composition (LSESCI) mines...
Slopes influenced by multiple faults are prone to large-scale landslides triggered multi-regional failures. Understanding the failure process and sequence is essential for sustainable development of mining operations. This paper presents a method combining InSAR monitoring numerical simulation analyze processes slopes affected faults. Using 298–710 m bench in central area eastern slope Nanfen open-pit mine as case study, multidimensional small baseline subset (MSBAS) technique was employed...
Backfilling is a common practice in the mining industry and backfilling performance plays significant role supporting surrounding rock mass. To evaluate performance, an experimental apparatus has been developed to understand how backfill affects compressive strength of sandstone specimens laboratory. Pebbles were selected model divided into six groups with different particle sizes using set standard sieves. The pebbles three types size compositions then produced, i.e. single gradation, two...
Joints often have important effects on seepage and elastic properties of jointed rock mass therefore the slope stability. In present paper, a model for discrete network is established using contact-free measurement technique geometrical statistic method. A coupled mathematical characterizing anisotropic permeability tensor stress was presented finally introduced to finite element model. case study roadway stability at Heishan Metal Mine in Hebei Province, China, performed investigate...
It is generally accepted that material heterogeneity has a great influence on the deformation, strength, damage and failure modes of rock. This paper presents numerical simulation rock process based characterization by using digital image processing (DIP) technique. The actual at mesoscopic scale (characterized as minerals) retrieved vectorization transformation method surface, it imported into well-established code Rock Failure Process Analysis (RFPA), in order to examine effect process. In...
Slope stability analysis is the most important problem in slope engineering design and construction. Open‐pit often spans several strata, many of which are relatively weak. There may be faults weak layers across whole rock. It very necessary to study instability mechanism multistratigraphic slopes with layers. In this paper, taking a complex three‐dimensional fault layer as research object, evolution laws stress field damage zone analyzed by using finite element strength reduction method....
Satellite remote sensing technology, with its ability to record spatial and temporal land surface conditions, has been extensively effectively utilized in evaluating mining environments. Western China, characterized by arid ecosystems, is a significant mineral resource area, boasting at least ten super-large bases, including coal, non-ferrous metal ores, mines. Surface activities, marked large scales, can exacerbate the fragility changes ecological environment vulnerable areas. Consequently,...
Uniaxial compression experiments and acoustic emission (AE) tests were conducted on weakly consolidated sandstone samples with bedding angle of 0°, 45°, 90° collected from Xiaojihan coal mine in Shaanxi Province, China; the characteristics investigated, including influencing mechanism characteristics, spatial distribution, b value changes AE activity. According to research, ringing counting rate energy are highest release is intense during loading process when these values decrease gentle...
Abstract This study investigates the Wangfu Depression of Songliao Basin, China, as a natural analogue site for Fe migration (bleaching) and mineralization (formation iron concretions) caused by reducing CO 2 ‐bearing fluids that leak along fractures after carbon capture, utilization, storage. We also examined origin fracture‐filling calcite veins, properties self‐sealing fluids, influence on compositions mudstone established bleaching model area. Our results show concretions are oxidative...
Stratified rock mass is a common structure and distributed widely on the earth’s crust. High-density distribution of stratified structural planes in has great influence mechanics properties mass, such as anisotropy stress seepage. Therefore, inherent characteristic that must be considered well slope stability. According to anisotropic characteristics an seepage-stress coupled model for mechanical behavior proposed based elasticity theory. The validated by simulating seepage fields idealized...
It is now understood that changes in fault dip angle significantly impact the mechanisms of stick-slip, including morphology slip surface, rate, and other critical aspects frictional mechanics. These make a vital factor influencing activation. Accordingly, there an urgent need for further research into mechanical properties evolution laws stick-slip instability movement under different angles. Microseismic Acoustic Emission (AE) monitoring are crucial tools studying as they can capture...
