Application of seismic monitoring in caving mines
Comprehensive and reliable seismic analysis techniques can aid in achieving successful inference of rockmass behaviour in different stages of the caving process. This case study is based on field data from Telfer sublevel caving mine in Western Australia. A seismic monitoring database was collected …

Assessing Thermal Comfort in Deep Underground Mines
… relative body comfort in deep hot underground mines is of great significance. This is because productivity, health, safety and the bottom line of mine operations depend on it. Comfort studies have been extensively researched, especially in the built and meteorological fields resulting in an …

Gateroad Design in Overlying Multi-Seam Mines
… duration of stress transferred from lower seam mines; and the second is to predict the effect of stress transferred from lower seam mines on opening stability. To solve these problems for both longwall and room-and-pillar mines, case study data were collected and analyzed to develop empirical …

Recoverable reserve estimation in multiple seam mines
A reliable estimate of minable coal reserves is essential for long-term planning and for conservation of energy resources. In the majority of the world's coalfields, seams are found on multiple horizons, and coal recovery may be significantly reduced depending upon the magnitude of seam …

Stress transfer between multi-seam longwall mines
The future of most underground coal mining in the USA will entail the extraction of coal under multi-seam mining conditions. Mine design in such an environment will require the accurate prediction of stress transfer between adjacent seams. The available knowledge on criteria controlling stress …

Ground penetrating radar investigations in Upper Kama potash mines
… surrounding underground openings in the potash mines is critically important for safe mining, planning the methods of extraction of an orebody, and preventing the influx of ground water. Continuous common offset ground penetrating radar (GPR) data were acquired in the potash mine operated by the …
