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,...
Though machine learning (ML) approaches have proliferated in the mechanical properties prediction of cemented paste backfill (CPB), their applications not reached peak potential due to lack more robust techniques. In present contribution, state-of-the-art ensemble method was employed for improved estimation unconfined compressive strength (UCS) CPB. 126 UCS tests were conducted on two new tailings provide an enlarged dataset. Tree-based ML approaches, namely, regression tree (RT), random...
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...
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 size distribution characteristics of fragments formed after loose blasting in open-pit mine will directly affect the economic benefits mining enterprise. impact load test coal samples with pressure ranging from 0.13MPa to 2.0MPa was carried out by using split Hope Pressure Bar Test System (SHPB). Based on theory stress wave attenuation, relationship between and laboratory is established. It concluded that increase pressure, degree breakage increases gradually. According requirement...
Based on the split Hopkinson pressure bar (SHPB) test system, dynamic impact tests of coal specimens under different pressures were carried out to study relationship between load and size crushed lump coal. theory stress wave attenuation, blasting in a single‐hole area seam applied an failure specimen laboratory was established. According characteristics fragmentation distribution destroyed requirement minimum cost control open‐pit mine, range divided into three groups: large‐diameter,...
The study of the permeability soil‐rock mixtures is important in supporting theories behind reclamation mechanisms for open‐pit mines. To avoid influence differences spatial distribution rock within same sample on a mixture laboratory tests, numerical method modelling based threshold control was proposed. Through statistical results 297 CT (computed tomography) cross sections samples, values pores, soils, and rocks are obtained, model representing reactions samples to real‐world conditions...
To address the scheduling challenges associated with increasing deployment of battery-swapping trucks in open-pit mines, this study proposes a multi-objective optimization model. This model accounts for unique characteristics by incorporating constraints related to battery swapping alerts, selection stations, and impact ambient temperature on capacity. The primary objective is minimize total haulage cost waiting time. Both genetic algorithm an adaptive are applied solve proposed aim identify...
Constructing a water‐blocking layer in the dump sites of an open‐pit coal mine is great significance to improve water retention capacity reclamation area. The permeability law costly be analyzed and researched by means field tests. In this study, soil‐rock mixture samples similar were prepared, rock block proportion (RBP) hydraulic pressure adopted as test variables conduct test, which provided theoretical support for on‐site construction. results show that when less than confining pressure,...
The strength criterion is an extremely important basis for evaluating the stability of surrounding rock and optimizing support pressure design. In this paper, nine different criteria are summarized simplified based on reasonable assumption. Then, a new unified equation established, which includes all theories proposed by paper. Meanwhile, closed‐form solution circular opening newly deduced with infinite finite external boundary combining nonassociative flow rule under plane strain...
