METHOD FOR MINING OF THICK SEAMS Russian patent published in 1995 - IPC

Abstract RU 2041355 C1

FIELD: coal industry. SUBSTANCE: method for mining of thick seams includes downward working of seam by horizontal slices with hollows and formation of forms of ventilation hollow from fabricated members. After formation of ventilation hollow from fabricated members, the latter are isolated from cementing mixture by filling a layer of broken coal. Fabricated members are installed at angle not exceeding the angle of broken coal natural slope. Broken coal is filled by coal continuous miner. EFFECT: reduced labor input in isolating operation. 3 cl, 3 dwg
