The present study conducted an extensive investigation into the durability of Na2SO4-activated binary slag cementitious materials for use in cemented paste backfill (CPB) under sulfate attack conditions. primary objectives were to assess feasibility employing a cost-effective and environmentally friendly binder CPB applications. Samples subjected exposure Na2SO4 MgSO4 solutions duration 30 weeks, multiple aspects including dimension stability, micro macro mechanical strength evolution,...
The synergistic utilization of multiple solid waste is an effective means achieving green filling and resource in mines. In this paper, the effects granulated blast furnace slag (GS) carbide (CS) as cementitious materials (GCCM) are investigated, along with their preliminary feasibility combination coal gangue (CG) bottom (FBS) for preparation backfill materials. hydration mechanism, mechanical properties, working performance GCCM GBC were studied, environmental impact cost-effectiveness...
Fiber reinforcement offers a promising solution to improve the mechanical performance and durability of cement-based foam backfill (CFB), addressing critical issues such as brittleness poor crack resistance under high-stress conditions. This study investigates effects polypropylene polyacrylonitrile fibers, at varying contents lengths, on flow properties CFB. A series experiments, including slump tests, rheology analysis, uniaxial compressive strength (UCS) pore structure scanning electron...
To address the current problems of poor seed-filling performance and seed leakage pneumatic filler for cabbage, we designed a disturbing precision cabbage based on auxiliary method. This seeder can completely perturb population entering bottom box casing during process, thereby increasing initial velocity seeds, facilitating smooth progress process. Firstly, carried out theoretical analysis particle dynamics process obtained influencing factors affecting seeder. Secondly, through EDEM...
In recent years, the Yellow River Delta has been affected by invasive species Spartina alterniflora ( S. ), resulting in a fragile ecological environment. It is of great significance to monitor ground object types wetlands. The classification accuracy based on Synthetic Aperture Radar (SAR) backscattering coefficient limited small difference between some objects. To solve this problem, decision tree method for extracting wetland combined time series SAR and coherence characteristics was...
This study was conducted on the impact of carbonization reaction performance gangue–cemented paste backfill(GCPB). Tests were using a box with CO2 concentrations 0%,5%,and 10%. Each test for 3,7, and 28 days. We then uniaxial compressive strength(UCS)testing, as well X-ray diffraction(XRD)and scanning electron microscopy(SEM)analyses to explore effects mechanical properties GCPBs under varying concentrations. The results showed that before days, UCS GCPB increased time. higher concentration,...
Winter wheat is one of the major food crops in China. It great importance to timely and accurately monitor winter cultivation for formulation agricultural policies. Therefore, effectively calculate planting information wheat, we proposed a method extracting from short-time series synthetic aperture radar (SAR) data. combines three new SAR indices, backscatter features, coherence features based on Sentinel-1 images October 2021 June 2022. First, coefficients were counted, newly constructed...
Analysis of rock acoustic emission characteristics in complete stress-strain process under uniaxial compression shows that the evolution deformation and damage can be divided into five stages—compaction, linear elastic deformation, accelerate inelastic development, plastic flow. Acoustic well reflect its compressive process. time series typical coal is comparatively dispersed presents group shock type. The frequency events their energy are bigger around point, but maximum amplitude secondary...
As a basic industry, the coal industry has greatly associated with development of national economy. The tight association This paper calculates direct consumption coefficient and complete among other economy sectors in an input-output model based on Input-Output Tables 2007, analyze reaction each sector to price fluctuation. results show that most top ten are sectors, which is influenced one production supply electric power heat power. If rises by 10%, this will accordingly rise 1.79%.
Abstract Significant interest has been focused on recovery rates, options, and utilization when tailings impoundments are re-mined. However, the stability of dams during process is also a severe issue. Based engineering geological survey laboratory tests, Tongling impoundment’s characteristics instability evolution under different heights diverse working conditions were analyzed by numerical simulation. Firstly, with help 2D software, position dam infiltration line alteration safety factor...
For a 4-wheel steering(4WS) electric wheel vehicle, the control strategy of 4WS and differential steering (4WS-DS) cooperative is studied in this paper. Based on idea hierarchical control, 4WS-DS divided into motion distribution layer. In layer, 7 degree freedom (DOF) vehicle model sliding mode controller are established to calculate additional yaw moment required maintain stability based error between actual reference states vehicle. established, working areas DS according sideslip angle....
