To effectively mitigate the hazards posed by blast waves of rock mass caving on closed walls during mining process, a stability prediction method based random forest (RF) algorithm is proposed, which designed to automatically identify key parameters. A machine learning model developed using algorithm, and its performance evaluated through accuracy, precision, recall, F1-score metrics. The probabilistic objective function constructed grid search hyperparameter optimization method, allowing...
Abstract This study aimed to investigate the formation mechanism of mud-inclusion-type underground debris flows natural caving mines. The characteristics fine moraine particles flowing through coarse-grained ore bed were used analyze process mud inclusions in a physical model test. Based on movement behavior bed, formation-mechanism generalized with was established. examine caving. results showed that had good cross-flow drawing ore. accumulation prerequisite for inclusions, and fluid formed...
A constitutive model based on damage mechanics and statistical strength theory for sandstone under water-rock coupling is proposed verified by laboratory tests numerical tests. The mechanism of the action water force clarified microscopic test rock in this paper. stress state determined analyzing results Based energy method, criterion interaction obtained, which introduced into considering rock; thus, a relatively perfect established. Finally, influence number cycles parameters was further...
The shear factor of ore drawing is an important affecting the formation underground debris flows. aim this study was to investigate effect mining on flows in natural caving. research background flow Plan copper mine, and we analyzed characteristics slurry material structure flow, as well influence ore-drawing mechanism flow. results showed that mine both a pseudoplastic thixotropic fluid. Shearing force induced deforms decreases its viscosity with increase rate time. produced by particles...
In order to verify the universal applicability of fluid structure coupling model analysis requirements deep tunnels under MIDAS-GTS geotechnical simulation environment, study, together with several mining enterprises, carried out verification and on measured data 107 in recent years. The reference group selects mean value results generated by using preferred nonfluid environment. Finally, it is confirmed that have significant advantages over within buried depth 550 ∼ 1450 m tunnel...
Rock-like damage and fracture are a common geological phenomenon. It not only affects the construction quality safety of project but also economic benefits. This study uses finite element method to calculate numerical simulation rock. Therefore, we must explore it improve success rate efficiency drilling under such problems. conducts systematic analysis through experimental research on theoretical knowledge internal failure stability rock-like masses other related methods. On basis...
