Problems solved by technology

At the same time, the tailings slurry is directly input into the hot pressing plant for neutralization treatment. After the gold concentrate is extracted, the remaining tailings slurry is pressurized pre-oxidized tailings neutralization slag paste material, which will be discharged into the tailings pond, resulting in a large storage capacity. pressure

Abstract

The invention discloses a method for carrying out grouting water control on ore by utilizing pressurized pre-oxidized tailing neutralized paste materials as grouting materials. The pressurized pre-oxidized tailing neutralized paste materials are selected as the grouting main materials, the grouting materials are formed by proportioning and mixing the pressurized pre-oxidized tailing neutralized paste materials, milltailings, cement and binding materials. The pressurized pre-oxidized tailing neutralized paste materials have a certain gelation function and cheap availability, through multiple times of tests and technological demonstration, after the pressurized pre-oxidized tailing neutralized paste materials are proportioned with the related cement and binding materials, the requirement offield grouting water control can be completely met, the cement quantity in the grouting material preparation process is reduced, the grouting water control cost is reduced, the grouting water controldifficulty is reduced, and safety of grouting water control is improved; and grouting water control mining is carried out by combining an underground mining method, and the problems that the underground sewer drainage cost is high and efficiency is low are changed.

Description

technical field [0001] The invention relates to the technical field of grouting water control for mining, in particular to a method for using pressurized pre-oxidized tailings neutralization paste material as a grouting material to grout water control of an ore body. Background technique [0002] Before August 2018, the Shuiyindong Gold Mine in Guizhou used dredging and drainage for flood control. During the development and mining process, there have been many water inrush accidents, and the mining conditions of the mine are currently mines with extremely complex hydrogeological conditions. In addition, due to The Ia ore body occurs in the structural alteration zone (Sbt) above the limestone strong aquifer of the Maokou Formation, and the dissolution fractures in the structural alteration zone are extremely developed, and the water-rich property is good. The mining of this orebody is directly affected by the alteration zone. Dissolution water and the limestone water of the u...
