Abstract

The invention provides a construction method for a cast-in-situ foam separation wall for tailing filling mining. The construction method comprises the following steps of: step 1, clearing a bottom plate and setting up a scaffold at the solid side of a mined-out inlet channel close to an inlet channel to be mined; step 2, fixing a force-bearing grating on the scaffold, and then hanging and bonding a separation cloth on the force-bearing grating; step 3, fixing the scaffold coated with the force-bearing grating and the separation cloth by a diagonal bracing, and surrounding a cavity with an open upper portion among the solid side, the bottom plate and the scaffold; step 4, injecting foam slurry in the cavity, and after the foam slurry is solidified to achieve a certain strength, detaching the scaffold, removing the force-bearing grating, and then obtaining the cast-in-situ foam separation wall. The construction method is rapid in construction, convenient to pour, and good in application performance.

Description

technical field

[0001] The invention belongs to the technical field of mining filling, and in particular relates to a construction method for quickly building a cast-in-place foam separation wall for tailings filling mining. Background technique

[0002] At present, for the mining of high-grade and thick ore seams, the filling and filling mining method is generally adopted. According to different filling materials, it can be divided into three types: dry filling method, water sand filling method and cemented filling method. Among them, the dry filling method is to use various transport machinery to transport the waste ore to the goaf for filling. Due to the low production efficiency, it is rarely used now; the water-sand filling method uses pumping or self-flowing methods to transport the high-water tailings solid-liquid mixture to the gob, and passes through the tailings after the water is filtered out. Fill achieved by deposition. The cemented filling method is to mix t...
