| Zusammenfassung: | FIELD: mining industry, particularly for underground mining of deep-seated mineral deposits. ^ SUBSTANCE: method of developing deep-seated water-bearing deposits involves carrying out working level excavation; drilling test unwatering well from excavated area to mineral deposit; performing preliminary reduction of underground deposit water head so that underground water level becomes under working level soil; carrying out hydromining within the limits of established roof pillar and deposit under working level by wells drilled downwards from working level; delivering the received mineral hydromixture to working level. Hydromining may be performed along unwatering well axes. ^ EFFECT: completeness of mineral extraction. ^ 2 cl, 1 dwg |
