Slope engineering is a type of complex system that mostly involved in water conservancy and civil mining engineering. Moreover, the link between slope stability safety quite close. This study took stable state as prediction object used unit weight, cohesion, internal friction angle, pore pressure coefficient, height indices to analyze based on collection 117 data points. The genetic algorithm was solve hyperparameters machine learning algorithms by simulating phenomena reproduction,...
The particulate pollution in the open-pit coal mines of China is particularly severe winter. aim this study to understand characteristics matter (PM) winter and provide a basis for prevention control pollution. We took problem PM concentration at bottom Haerwusu Open-pit Coal Mine (HOCM) as research object. Dust monitoring equipment two measurement points different heights were positioned continuous concentration. data three months gathered. Statistical analyses performed analyze variation...
Dust is a severe environmental issue in open-pit mines, and accurate estimation of its concentration allows for viable solutions control management. This research proposes machine learning-based solution accurately estimating dust concentrations. The proposed approach, tested using real data from the Haerwusu coal mine China, based upon integrated random forest-Markov chain (RF-MC) model. forest method used estimation, while Markov correction. wind speed, temperature, humidity, atmospheric...
Dust pollution in open-pit coal mines severely restricts the green development of mines. Therefore, dust control has become an important requirement for sustainable mining industry. With goal prevention and mines, this paper puts forward concept a non-disturbance area mine. It clarifies characteristics generation, coverage area, particle size distribution area. Taking at dump site as example, study comprehensively utilizes indoor tests field to develop suppressant determine its suppression...
Introduction Winter dust pollution in China’s northern open-pit coal mines is serious, and the prevention control of winter one important problems construction green mines. Methods In this study, we collected concentration data, meteorological production data from experimental mine 1 December 2018, to 28 February 2019. The characteristics changes factors, intensity during cold period are introduced, correlation between these factors was analyzed using multivariate statistical analysis...
Abstract Dust pollution from Chinese open-pit coal mines (OPCMs) threatens the coexistence of resource development and environmental protection. This research introduces a new approach to designing OPCMs based on meteorological indicators for dust removal diffusion. It analyzes production, distribution, emission features large-scale in China. The factors affecting dispersion atmospheric characteristics were also examined. findings reveal surge number output OPCMs, intensifying conflict...
This research proposes a new dust reduction method based on water infusion blasting in order to effectively minimize the production during open-pit mines. The proposed was applied at Haerwusu coal mine, China. A high-speed camera used record dynamic process of generation blasting. images acquired from main locations were analyzed using gray level recognition MATLAB. then numerically simulated ANSYS/Fluent software. Finally, field experiment conducted verify by analyzing its efficiency....
The coal shed is an enclosed space where raw stored and handled. intensive operation of the machinery inside generates a large amount dust, wind speed easily leads to high concentration which endangers physical mental health workers. In this paper, we first studied particle size distribution dust samples in found that 12.2% air was 10–100 μm, 87.8% less than 10 72.9% 2.5 μm. Fluent used simulate law dispersion under different working conditions, finally, simulation results were guide design...
As an important link in open-pit mining production, the crushing station produces a large amount of dust during production process. Dust has characteristics wide spread area, great harm, and difficult governance. Therefore, control become key issue that needs to be solved mining. In this article, we assess results after high-speed cameras concentration detectors are installed around monitor surrounding air. It is found air, with particle size less than 2.5 μm accounts for 67.43%, 10 17.30%,...
To further promote dust control efforts in Chinese open-pit coal mines, this study focuses on the research of and rock produced by different explosions Haerwusu mine China. By investigating relationship between physical chemical characteristics particles from mines wetting properties dust, main factors influencing explosive are identified. This provides a theoretical basis for subsequent work mines. Simultaneously, to formulate more effective suppressants reduce pollution, conducts...
Remote Sensing Image Change Captioning (RSICC) aims to generate natural language descriptions of surface changes between multi-temporal remote sensing images, detailing the categories, locations, and dynamics changed objects (e.g., additions or disappearances). Many current methods attempt leverage long-sequence understanding reasoning capabilities multimodal large models (MLLMs) for this task. However, without comprehensive data support, these approaches often alter essential feature...
