FIELD: mining.
SUBSTANCE: invention relates to ecology, particularly to techniques of rehabilitation of disturbed lands during performance of drilling operations in the process of well construction under the conditions of eternal frost. The recultivation method includes purification of the liquid phase, mixing drilling wastes with peat. The liquid phase is frozen up, the pieces of ice are placed on the bottom of the sludge pit and covered with a layer of the mix of drilling wastes with peat.
EFFECT: mitigation of negative impact on the environment and reduction of material expenses for recultivation of sludge pits.
