Dismantling guide
In mining, mining management refers to the organizational options for managing mining . This applies in particular to the possible variants with regard to the location and movement of the mining within the deposit .
Influences on the mining management
The mining management is mainly influenced by the shape and geological design of the respective deposit . So it is of great importance for the mining management to know the particular deposit to be mined as precisely as possible. This applies not only to the usable minerals , but also to the adjacent rock . It is important to know the thickness of the deposit in order to be able to decide in advance whether and how the deposit will be subdivided. It is necessary to have knowledge of bed surfaces , natural dividing surfaces and boundary surfaces of the adjacent rock in order to be able to lead the mining accordingly.
Application of the removal guide
The decisive task of the mining management is to determine how the mining should take place within the deposit. Here it is necessary, based on the knowledge about the structure of the deposit, to organize the mining accordingly. When setting up the deposit, it must be decided in advance whether the mining should be single-wing or double-wing. So whether the deposit is only dismantled on one side or on both sides from a chopping up, and whether the wings should be dismantled one after the other or at the same time. According to the mining management, the respective mining operations are spatially distributed in the mine building . The timing and sequence for dismantling the individual operations must also be determined. This is particularly true in the case of several adjacent sections within the same deposit. It is also part of the mining management to divide the deposit into disks or banks. The following principle applies here: "The deposit must always be dismantled from top to bottom." Ultimately, the direction is determined on the basis of the mining guide, ie whether a mining operation is carried out in front or in dismantling . There is also the option of combining both construction methods and operating them as a "combined front and back construction".
Influences of the mining management
The mining management influences the mining of the deposit in different ways. The choice of direction depends on the particular mining method . As long front-like designs like this one may longwall be carried out both in the front and in the dismantling. With other construction methods, you are not entirely free to choose your direction. The pillar-like construction methods only allow dismantling. In spatial distribution of mining operations, the length of which is reducing distances a key organizational factor. Long stretches of mining have an impact on ventilation and the mine climate . Particularly in hard coal mines with gaseous coal, the ventilation chosen according to the mining management has to influence the methane content in the fresh and waste weather . The mining management also influences the outgassing in the chronological order of the mining operations . Since the outgassing is greatest in deposits that have not yet been scorched, the outgassing can be reduced accordingly by building over or undercutting a seam section.
