A mining environment reconstruction method based on the recycling of waste tires

Abstract

The invention discloses a mining environment reconstruction method based on the recycling of waste tires, which comprises the following steps: overlapping and gluing a plurality of waste tires together to form a series of waste tires, and the cavity of the series of waste tires constitutes a tire filling area ; Use ore pillars as corners, and multiple waste tire series arranged side by side to form a central filling area; arrange water filter pipes in the tire filling area and the central filling area; inject tailings cement slurry into the tire filling area for maintenance to the target Strength: fill the central filling area in layers, and when the central filling area is filled to the last layer, the top filling of the central filling area is realized in the form of circumferential multi-point filling. The mining environment reconstruction method of the present application uses waste tire solid waste as the main component of the filling body construction, which not only improves the construction efficiency, but also greatly improves the impact resistance of the filling structure, and reduces the damage of the blasting shock wave to the filling structure. Thus, the safe and efficient recovery of residual ore is realized.

Description

technical field [0001] The invention relates to the technical field of mining environment reconstruction and filling during the recovery of residual ore, in particular to a mining environment reconstruction method based on the recovery and utilization of waste tires. Background technique [0002] "Green mine" has become the ultimate goal of mining enterprises. The filling mining method has been widely used in mines at home and abroad because it can efficiently utilize mine solid waste, improve resource recovery rate, and reduce dilution rate. However, due to the constraints of the ore body environment, mining methods, and surrounding rock conditions, mine filling cannot be accomplished overnight. Especially in the mines mined by the room-and-pillar method, the extraction of rich ore or higher production capacity was pursued in the early stage of production, leaving behind a large number of scattered and irregular ore pillars. The ore pillar has been exposed for a long time...

AI Technical Summary

Problems solved by technology

[0003] For the recovery of residual ore left by the room-and-pillar method, some researchers have proposed the cofferdam filling mining method. However, the implementation process of this method is cumbersome, requiring the construction of large-scale scaffolding, and the construction efficiency is low.

Furthermore, as a conventional filling body is a low-strength rock-soil material, the reflection and stretching effect of the stress wave on the surface of the filling body is particularly obvious. When subjected to the impact of the stress wave, it is very easy to peel off or even collapse on the free surface of the filling body
