01.05.2016 · Recent years, underground mining method is becoming popular because of its potentially high productivity and efficiency. In this method, a mining machinery; load haul dump (LHD), is used as both an excavator and a transporter of ore. This paper proposes a distributed system that realizes the excavation and transport functions with separated vehicles, an excavator and a transporter. In addition ...

Backfilling mining is thought to play a significant role in controlling the deformation of coal and rock strata and the distribution of underground pressure. This study presents a numerical investigation of the influence of the strength of backfilling materials (BMS) on the deformation of coal and rock strata consisting of multiple goaf during excavation using the backfill mining method. In ...

In mining, the underground assembly or power centre is engineered to transform and distribute electrical power brought underground. This assembly typically includes a medium-voltage incoming circuit breaker or switch with current-limiting fuse (see Fig 1). Fig. 1: Low-profile underground assembly including primary fused switch, transformer and low-voltage circuit breakers. The device protects ...

The object of research is the technology and facilities for underground mining of ores in the disrupted massifs. One of the most problematic places is the formation of man-made voids; which influence the occurrence and redistribution of stress-strain state (SSS) of the rock massif. Their existence in the earth's crust provokes the influence of geomechanical and seismic phenomena; up to the ...
