A method for blocking the damage of the old flood drainage system of the tailings pond

Abstract

The invention discloses a new method for blocking the breakage of an old flood drainage system of a tailings pond. The new method comprises the following steps: firstly constructing and laying a reverse filter gland (1) in an outlet position of the old blood drainage system (3); then drilling and penetrating through the outer wall of the old flood drainage system (3) from an old blood drainage system building top plate (10) to an old blood drainage system building bottom plate (11) in a tailings accumulation dam of the tailings pond by adopting a drilling machine of which the external diameteris 89 to 110, thus forming an in-pond grouting hole (2); carrying out pressurized pouring of comprehensive slurry on the in-pond grouting hole (2), and blocking a leakage passage in a building of theold flood drainage system (3). According to the new method disclosed by the invention, an effect of draining water without sand leaking can be rapidly achieved in the outlet position of the old flooddrainage system of the tailings pond, a large amount of blocky condensation bodies can be formed in the old flood drainage system of the tailings pond within a short time so as to block the leakage passage, high safety and high reliability are obtained, the cost is low, other potential safety hazards in a later period cannot be generated, and blocking requirements after the breakage of the old flood drainage system of the tailings pond can be met.

Description

technical field [0001] The invention belongs to the technical field of safety management of tailings ponds, and in particular relates to a method for sealing the damaged part of the old flood discharge system of the tailings pond, and is especially suitable for sand running and leakage caused by damage to the old flood discharge system during operation and use. The safety management of the slurry tailings pond can eliminate the danger and restore the normal operation of the tailings pond. Background technique [0002] Tailings pond is an important facility of mining enterprises. It is a high-level debris flow hazard source formed by human accumulation, and it may also be a source of environmental pollution; tailings pond is currently recognized by laws and regulations as one of the major hazard sources of non-coal mines; The flood system is an important safety facility for the tailings pond. The normal operation of the flood drainage system and the timely disposal of acciden...
