Title: Hydraulic transport of mined material to the surface - the material being fed to a low pressure circuit and transferred to a high pressure delivery circuit
Inventor: FUNK ERWIN DUANE
IPC: B65G53/30
Filed: 1977-12-30
Abstract: Equipment for hydraulically conveying mined material, e,g coal, from the mine face to the surface consists of a low pressure circuit (Ie into which the material is injected and a high pressure circuit (II) which receives the material from (I) and delivers it to sepn. equipment on the surface. The exchange of material from (I) to (II) takes place inside a rotor with ports which open alternately to the two loops. A screen mounted in rotor housing passage which is the (I) outlet line retains all but the finer material inside the rotor from where it is then flushed into (II) when the rotor in turn lines up with this. The equipment can be mounted on a movable platform with high pressure flexible connections to the high pressure lines so that it can move forward into the mine in conjunction with the mining machinery. It can be adapted to work in a seam where headroom is limited and may employ more than two transmission circuits in which case the second exchange rotor equipment may be designed for the high hydraulic transport pressures required and may be mounted in a fixed location. The hydraulic transport system avoids dust hazards and leakage from (II) at the exchange equipment passes into (I) rather than the mine.
