The Relationship

During surface-underground combined mining, the method to control the ground air leakage is adopted by the capping layer using the fragmented rocks and the discarded tailings. In order to study the air leakage characteristic with the capping, the porosity of the rock particles of seven sizes and the air leakage characteristics of the capping were studied and the relationship between the air leakage coefficient and amount of air leakage with the capping height were found basing on the laboratory analogue simulation tests. It can provide the theoretical basis for determining the capping height of iron mine.
