PROBLEMS RELATED TO RECULTIVATION OF MARITSA-IZTOK COAL MINE DISTURBED TERRAINS OF AGRICULTURALLANDSVILEN RAYKOV, IVAN DIMITROV 11 Shumen University “Ep.K.Preslavski”, e-mail:rajkov_svilen@abv.bgKеy words: recultivation, problems, solutionsABSTRACTAn analysis is made on problems related to recultivation of Maritsa-Iztok coal mine disturbedterrains of agricultural land. New decisions for direct implementation are described for recovery ofsoil fertility of disturbed lands and problems related to the different technological measures. Onanalysing the conditions for reclamation with agricultural purposes, it was concluded that the mostimportant aspects are of technological and climatic character. We recommend that corrections aremade in the technological activities of the technical and biological recultivation. The development ofa special agricultural system is required and technologies to grow siderate crops.Any amelioration practice which does not reflect the actual conditions may cause a risk to the wholetechnology of reclamation of disturbed lands.In the region of Maritsa-Iztok coal mine in the open mining large areas ofarable land are destroyed. The opening lands covered so far the more than 10000ha of agricultural land. To use these areas for farming or reforestation of foresttypes it is necessary to restore their fertility through the application of technical andbiological reclamation.The technical recultivation includes placement of materials on their fitness,leveling the ground and adjusting the area. Biological reclamation involves theselection of plant species, treatments, fertilization, introduction of regular sowingrotationand other agricultural activities (Treykyashki, Hristov, 1982).Along with the approved reclamation regulation in recent years newsolutions are searched for reclamation of damaged areas, primarily in bioremediationstage.In reclamation making more acute arises a number of problems.Compliance therewith is mandatory, and finding adequate solutions to overcomethem is related to the successful conduct of operations.The purpose of this report is to mark the attendant problems ofimplementing new technology solutions for the reclamation of damaged areas inthe region of Maritsa - Iztok.A number of technological solutions is developed and proposed forimplementation in practice:- Use of siderates – “Alternative biotechnological method for the recoveryof soils “93
