Substantiation of ways to reclaim the space of the previously mined-out quarries for the recreational purposes

Abstract

Opencast fields mining leads to land disturbance when conducting mining operations and storing of overburden rocks. The timely reclaiming of the disturbed lands according to the legislation requirements is an immediate duty of the subsoil user. The reclamation of the previously mined-out space of quarries refers to an extremely important tasks of the mining enterprise. The use of water management direction in reclamation assumes the use of previously mined-out space of a quarry to create the water reservoir through various methods of rehabilitation. There are presented various ways of designing the coastal zone of the created artificial water reservoirs in the previously mined-out space of the quarries located worldwide, which are used for the recreational purposes. The various profiles of slopes of artificial water reservoirs in a quarry with more low gradients, suitable for swimming and recreation are shown. Designing of a coastal area on the site of a quarry, intended for water reservoirs, depends on the water level position in the created body of water. The water reservoir, as the lake of artificial origin, created on the former quarry site, is shown. The purpose of the article is to substantiate the methodological approaches and engineering solutions concerning reclamation of the mined-out space after the opencast mining for the recreational purposes.
