In view of the coal dust concentration measurement elements, the measurement pollution environment will reduce the measurement accuracy. The paper proposes a soft measurement method of mine dust concentration based on the K-RBF neural network theory. It takes the electrostatic signal as the measurement signal and extracts the short-term energy, RMS and rectification value of the electrostatic s...

In order to reliably monitor the operating status of one-way aerial ropeways for underground mine and better guarantee the safety of mine personnel, a hierarchical routing protocol based on energy efficiency and chain-type structure is proposed in this paper. Previous studies show that uniform cluster formation can prolong the lifetime of network. So a novel time allocation algorithm based on t...

The dominant working structure of an underground mine is a set of interconnected tunnels which provides access to ore zones and haulage of ore from the designated ore zones to the mill. This set of interconnected tunnels forms a network. We describe a mathematical network model and the modelling features of our two software tools for designing underground mine layouts that minimise associated c...

Shaft sinking is one of the main parts in underground mine planning. Shaft has various applications in underground mines e.g. minerals exiting flow, gases entrance or exit way, stope developments for exploitation etc. Considering that this section requires an abundance of expenses, management always following the election is the way that both terms have the technical considerations, economic co...

Carbon monoxide (CO) and carbon dioxide (CO2) emissions during a spontaneous heating event in a coal mine are important gases to monitor for detecting the spontaneous heating at an early stage. However, in underground coal mines, the CO and CO2 concentrations and their related fire ratios may be affected by mine ventilation. In this study, CO and CO2 emissions from spontaneous heating of a U.S....

The behavior of rope-guided conveyances is so complicated that the rope-guided hoisting system hasn't been understood thoroughly so far. In this paper, with user-defined functions loaded, ANSYS FLUENT 14.5 was employed to simulate lateral motion of rope-guided conveyances in two typical kinds of shaft layouts. With rope-guided mine elevator and mine cages taken into account, results show that t...

According to the shortcoming of traditional artificial management mine-maps, the solutions of dynamic management digital mine-maps were proposed. Analyzing of the main tasks and characteristics in lifecycle stages of mining engineering maps, based on the idea and meaning of lifecycle, first we divided mine-maps lifecycle into seven stages, such as design drawing task assignation, design drawing...
