The article focuses on substantiation of such parameters heavy-duty sandwich belt high angle conveyors as the width to ensure operation without spillage load, and hugging pressure with regard its dependence length conveyor. It is noted that incorrect estimation these can lead redistribution forces between conveying belts increasing load applied belt. economic efficiency considered in comparison...

This study proposes an incremental extreme extraction method based on the waveform characteristics of ground vibration signals obtained from open-pit mines to investigate distribution and deep-hole blasting. Firstly, is proposed borehole blasting in mines. The could extract screen values effectively improve utilization rate data. space vector particle introduced analyze angle change between vel...

determination a sequence of extracting ore is one of the most important problems in mine annual production scheduling. production scheduling affects mining performance especially in a poly-metallic open pit mine with considering the imposed operational and physical constraints mandated by high levels of reliability in relation to the obtained actual results. one of the important operational con...

Almost all post-exploitation open pit mines in the world are shaped as a final water reservoir. One of main hazards is slope stability lake banks. To develop reliability methodology for assessing long-term flooded open-pit lake, back analysis was conducted using 2D and 3D large-scale numerical models Lake Most, which one largest mining lakes Europe (Czech Republic). The model built, based on si...

The information obtained using the satellite technologies of remote sensing provides new massive knowledge about open pit mining operations at deposits carbonate rocks for manufacture cement in 26 regions Russia. number and haulage machines operating each individual mine within whole industry sector is determined. was used analytical estimation capacity overall potential production this sector....

This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...
