FIELD: mining.
SUBSTANCE: invention refers to mining industry, and namely to the method used for hydraulic filling of long single mine workings. It involves influence of retaining and filtering connection straps, installation of pulp pipeline, and supply of filling pulp. Water is drained via drain holes made in connection straps installed on the side opposite to the pulp supply. Filling pulp is supplied to the filled area via pulp pipeline with the holes made in lower part, which is attached to the roof of mine working throughout its length. The holes made at the beginning of the pipeline are equipped with petal valves.
EFFECT: increases the filling degree of the worked-out area in hard-to-reach sections.
