MINING COMBINE AND METHOD FOR CONTROLLING DEPTH OF MINING COMBINE EXTRACTING MEANS LOCATION Russian patent published in 2005 - IPC

FIELD: mining industry.

SUBSTANCE: mining combine has extraction means, on which a body is mounted, having at least one first liquid outlet, for supplying liquid to material. Pipeline, through which liquid is fed to first liquid outlet, contains means for measuring flow and/or pressure of liquid in pipeline, for determining, in which of to layers outlet is positioned. Combine can have at least one second liquid outlet, placed in such a way, that first liquid outlet is in lower layer, and second liquid outlet is placed in upper layer. First liquid outlet can have one of multiple first liquid outlets spaced from each other, and second liquid outlet - one of multiple spaced from each other second liquid outlets. Efficiency of liquid flow through multiple spaced first outlets can surpass those of multiple spaced from each other second liquid outlets. Placement of second liquid outlet in separate body cover is possible. First and second liquid outlets can be directed downwardly relatively to direction of mining combine displacement. Method for controlling depth of position of mining combine extraction means includes placing two liquid outlets, interacting with material extraction means, in a material, while second liquid outlet is placed above first liquid outlet, liquid is fed to first and second liquid outlets and flow and/or pressure of liquid is measured. Layer, wherein liquid outlet lies, is detected, and first liquid outlet is placed in lower layer and second liquid outlet is placed in upper layer, to determine depth of position of extraction means relatively to two layers.

EFFECT: higher precision.
