Problems solved by technology

At present, the comprehensive utilization rate of tailings in making sintered bricks, steam bricks and filling goafs is less than 10%, and the processing cost is relatively high. Only filling goafs requires 60-70 yuan of cement for processing one ton of tailings sand. consolidation
The main way to deal with a large number of iron tailings that have not been comprehensively utilized is to pile them up, which not only forces enterprises to build tailings ponds and bear high infrastructure costs, but also takes up valuable land resources

Abstract

The invention discloses a construction method of clay-improved tailing sand roadbed filler. The method comprises the following steps: 1) cleaning the ground surface; (2) preparing materials; (3) processing a substrate; (4) spreading the material; (5) rolling the filler; and (6) setting longitudinal drainage channels. The method uses the industrial waste tailings as the roadbed filler, and improves the performance of the tailing ore used for road by adding the clay, ensures the quality of roadbed, and realizes the recycling and efficient utilization of waste.

Description

technical field [0001] The invention relates to the technical field of roadbed fillers, in particular to a construction method for clay-improved tailings sand roadbed fillers. Background technique [0002] Tailings are the part with the lowest content of useful targets in beneficiation operations. According to incomplete statistics, the total amount of tailings stockpiled in the country exceeds 10 billion tons, and it is still growing at a rate of about 10% every year. At present, the comprehensive utilization rate of tailings in making sintered bricks, steam bricks and filling goafs is less than 10%, and the processing cost is relatively high. Only filling goafs requires 60-70 yuan of cement for processing one ton of tailings sand. Consolidation. The main way to deal with a large amount of iron tailings that has not been comprehensively utilized is to stack them, which not only forces enterprises to build tailings ponds, bears high infrastructure costs, but also occupies ...
