ethod of mudflow geotechnological development of minefields // 2391511
FIELD: mining.SUBSTANCE: solid mass is subject to alluvial re-deposition with water flow. For that purpose, above the level of minefield section there created is water reserve, and in the minefield section there opened is some part of reserves with pioneer ditch.
