Method of Redevelopment of Underground Mining Facilities

Abstract

Mining is a set of industrial branches engaged in exploration, extraction, primary processing and obtaining the initial semi-finished product of elements related to minerals. Deposits are ore, non-metallic and alluvial. These deposits are mined by open pit and closed pit methods. After the end of underground operations, empty mine fields remain, which on the surface are labeled as exclusion zones. The problem of cave-in zones, under which the waste mine fields of the mining industry are located, has been particularly acute for decades. These mines are located not only under the industrial zones of populated areas, but also under residential and public areas and cause irreversible transformation of the natural environment, which leads to catastrophic consequences. Transformation of underground space is the main task of redevelopment of industrial areas of this kind. It is possible to build underground structures for other purposes in worked-out mines. Due to the fact that these structures will be maintained and operated, the change in the secondary stress fields in the mountain massif will not have such catastrophic consequences as in the case of alienation-collapse zones. Besides, the reuse of worked-out workings is economically more favorable due to the fact that sinking will be minimal. In this paper only underground mining complexes and the possibility of their reuse will be considered.
