The design and scheduling of open-pit mines are considered as an important and intricate problem in mines planning. The optimal extraction sequence is obtained by the production schedule by maximizing the net present value. The long-term production scheduling optimization problem (LTPSOP) of open-pit mines is a lot-sizing, mixed-integer programming (MIP) problem that should be solved in reasonably limited time due to the operational requirements. The current paper presents a new solution approac...
The main research content of this paper is VR visualization allocation algorithm which can realize memory optimization. The use of this algorithm can effectively reduce the redundancy of modeling and centralized processing of multiple models, reduce the time consumption, improve the efficiency of modeling, and ensure the smooth operation of VR visualization system. It is important to note that the economic development of the region will affect the visualization effect, especially when studying t...

In recent years, with the continuous construction of highways in Southwest China, highway tunnels inevitably have to pass through mine tunnels, which often happen. The tunnel passing through the coal mining area has an adverse impact on the stability of the rock around the tunnel, which leads to the instability of the rock around the tunnel and may collapse. It is of great practical significance to analyze and study the stability of surrounding rock in the section of highway tunnel crossing the ...

In open-pit coal mines where burned rock occurs, because the burned rock is fragile and contains a large number of fine particles, a large amount of dust will be produced in the process of mining and loading. The dust concentration is as high as 2500mg/m3 on average, which seriously affects the health of the workers in the open-pit mine and the atmospheric environment in the mining area. In order to control the dust disaster in mining and loading face with burning rock, the dust diffusion concen...
In this article, cutting parameter models (Fc, Ft, and Ec) and the processability index in the processing of 3D marble products with a milled tool with a computer numerical control (CNC) machine are examined. For the experimental studies, seven types of natural stones, 4.0-mm-diameter end mill set, thirteen different cutting depths (dp) between 0.1 and 2.0 mm, and 5 different feed rate (Va) parameters between 2000 and 4000 mm/min were selected. Chemical properties, mineralogical and petrographic...

The pullout behavior of plate anchor embedded in clays has received significant attention from researchers, but most existing studies are limited to plate anchors in single layer of undrained clay. In this study, the vertical pullout capacity of horizontal strip anchors in undrained two-layered clay is investigated. A series of finite element analyses were carried out to obtain the stability predictions for a wide range of geometrical and soil properties. Anchor-soil interface conditions of imme...
