belt rip control in underground chutes


Information Management System For Underground Mining ...

Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining countries.

Chute flow patterns are described and the application of chute flow dynamics to the determination of the most appropriate chute profiles to achieve optimum flow is illustrated. The influence of the flow properties and chute flow dynamics in selecting the required geometry to minimise chute and belt wear at the feed point will be highlighted. 1.

Improved methods of dust control in the metal and nonmetal mining industries were studied. Preliminary dust surveys were made at selected mines and three mines were chosen for additional studies. Dust control effectiveness was evaluated using full-shift gravimetric sampling and dust monitor readings. Analyses for free silica content and particle size distribution were conducted.

Belt control normally consists of the net sum of the belt permissives, the operator start/stop stations, the start warning system, interlock sequencing of individual conveyors and other process controls. Belt control initiates a run command to the drive controller. Sometimes the belt control issues a running reference speed to the drive controller.

A dial on the control box can be set to delay the opening of the chute from 3-30 seconds after the remote button is pushed. This allows the roper to prepare for the run after pushing the release button. Our preprogrammed Remote Control unit is compact and easily fits in a pocket or in the leather belt clip case (sold separately).

Belt-Over-Belt Conveyors There are some applications, such as moving flexible pouches, where cleated conveyors don't work as well for incline movement. Flexible pouches tend to be more delicate and if the pouch lands incorrectly on a cleat, the bag could rip, leading to costly downtime to clean the conveyor as well as product loss.
