Abstract

The invention discloses a full tailing filling method in large goafs, which is realized by the technical scheme with the following steps: dividing the combination of relatively independent and adjacent single or a plurality of goafs (6) into a filling unit; building a sealed wall (8) on a tunnel (7) at the periphery of the goafs (6) of the filling unit, arranging a drain pipe (9) in the wall bodyof the sealed wall (8), and arranging an ore pulp valve (10) on the drain pipe (9); laying a tailing conveying main pipe (3) above the filling unit through an adit (2) above the goafs (6); connectingeach upper opening of the filling unit to one or a plurality of hydraulic sand filling pipes (4) through the tailing conveying main pipe (3); and discharging sand at high levels, discharging water indifferent middle sections, and filling alternately. In the invention, full tailings are used for filling the existing goafs, thereby eliminating the potential safety hazards of the goafs, ensuring the normal production of large deep well mines, saving the treatment cost, the tailing stockpiling and land acquisition cost and the drainage cost of the goafs, realizing the purpose of less-waste and no-waste exploitation, and taking an demonstration effect on constructing ecological mines.

Description

technical field [0001] The invention relates to a method for treating goafs in underground mines, in particular to a method for filling tailings in large-scale goafs. It is suitable for all types of mines to use full tailings to fill existing goafs. Background technique [0002] There are two basic methods for gob processing: one is the caving method, and the other is the filling method. Using industrial waste such as whole tailings as backfill to treat gobs or store them as storage, the current engineering examples at home and abroad are limited to dry sand or relatively coarse tailings. For the large-scale mined-out area located in the upper part of the mining stope, it is a technical problem with large project scale, complex geological conditions and high risk to use very fine-grained tailings for hydraulic filling. The main manifestations are large height difference, high fluid pressure, small space for sand discharge outlet, low concentration and large flow rate, slow...
