METHOD OF HYDROMECHANICALLY BACKFILLING A LAND IN PARTICULAR THAT AFTER SULFUR MINING THROUGH BORE-HOLES

摘要

1. Hydromechanical method of silting ground, in particular ground from which sulphur has been mined, using an isolating and filling material, preferably flotation tailings with granularity of up to 1.0 mm, carried out on previously embanked ground using distribution pipelines, characterized in that in the principal directions of the ground being silted (1), drops are made for water to run off from the embankment (3) towards the lowest level, and the distribution pipelines (5), in whose lower part are outflow holes (5a) with differing diameters, are spaced at distances not greater than 80 m from each other, so that the settling cones (12) formed under them do not cause separation of the flotation tailings, but by overlapping with each other gradually fill the ground being silted (1), while the distribution of the flotation tailings starts from the furthest or/and highest point of the ground being silted.IMAGE
