Cemented Filling in a Certain Old Iron Goaf

Abstract:

The management of old goaf is always the emphasis and difficulty in our mining industry. And the filling method is a important means for managing the old goaf. Taking a certain old goaf in ZiBo as an example, the article in detail introduced the process of old goaf management, proposed methods of regulating the quality of filling materials, constructing a new downhole water filter wall and controlling concentration of solution value in 53% to 55%, to strengthen the quality of concentration of solution. Based on this, the strength of filling body is 0.6Mpa more than the designed requirement, which can bring the good experience for similar researches.
