NIOSH has developed an automated PC-based seismic event (induced earthquake) monitoring system for use in mine ground control studies. The distribution and coordination of data acquisition and processing functions across a local area network is a central feature of the system. Mine-wide installations utilize multiple, autonomous seismic networks located both underground and on the surface. Seis...

Further research has been done in order to reduce the energy consumption of the mine roadway wireless sensor nodes and prolong the lifetime of the network. On the basis of analysis and study on the existing linear wireless sensor network nodes deployment, the node distance optimization deployment scheme with sinks in the center is proposed. The calculation method for optimized distance between ...

LavaNet consists of a series of scripts written in Perl that give access to a neural network simulation environment inside a general mine planning package. LavaNet enables easy development of neural network training datasets using information from any of the data and model structures available, such as block models and drillhole databases. Neural networks can be trained inside the mine planning...

We propose and evaluate a neural network approach to mine detection using Electromagnetic Induction (EMI) sensors which provides a robust non-parametric approach. In our approach, a neural network with the well-known back-propagation learning algorithm combines the SStatistic with the δ-Technique to discriminate between non-mine patterns and mines. Experimental results show that this approach r...

Due to the complex spatial hierarchy and large network scale of mine ventilation system, it is difficult obtain information all branches in real-time, accurately, comprehensively by arranging sensors. To overcome this difficulty, paper proposes an optimal layout method sensors based on DETMAX algorithm Tabu search algorithm. Given a known number sensors, proposed can efficiently select set arra...

For given environmental conditions, such as temperature, pressure, relative humidity, velocity air, distr...

Underground fires are still one of the most significant risks in mines today. In order to manage this risk, it is necessary know potential evolution a fire and effects can have on people other objects. Ventilation plays an essential role development fire; also influences propagation toxic fumes variation temperatures all areas mine. Currently, possible jointly analyze, through numerical modelin...
