Basic route
As a basic line is referred to in the mining the deepest striking , i.e. in a certain direction running, route . In ore mining, a basic route is also referred to as a gezeug route, field site route or runs.
use
A basic route is primarily used to develop a mine field . In particular, the behavior of the deposit and the adjacent rock should be explored through the base section . Based on the knowledge gained, the mining method to be used later and the appropriate dimensioning of the cutting length can be determined. Construction departments that are still on the road can be accessed from the basic route if they have not already been opened up by crosscuts . Basic routes are mainly used in pit fields with a short striking length or in deposits with good adjacent rock. Even with very thick deposits, basic routes are preferred. In addition, the basic stretch is also used for pumping and drainage . Part of the deposit will later be dismantled from the ground. The passage of time when deeper deposit parts are dismantled, the old basic line is used for ventilation of the next deeper sole . In construction areas, in which the orientation of the network by means of the main conveyor lines, in conjunction with cross-section blows basic routes are rarely ascended. Even if the behavior of the deposit is known from neighboring mines or from mining on the upper levels, the increased excavation of basic stretches is often dispensed with. In particular, where the recovery was used in the upper mining operations , the excavation of the basic routes is completely dispensed with during the installation phase and these are only created together with the mining.
Driveway
The basic sections are from the cross-cuts starting in the deposit ascended . Since basic stretches are often driven in unscratched mountains, special attention must be paid to ventilation. The reason for this is the methane often stored in the rock or, in some cases, carbon dioxide . This applies in particular to hard coal mines that are at risk of firedamp and also to rock salt and potash mines. To improve the ventilation, an auxiliary route is therefore either built parallel to the base section or above the base section. Depending on the deposit, the basic stretches will be provided with rectangular or round stretches . Particularly in the case of deposits of small thickness, the height of the deposit is often not sufficient to achieve a sufficiently large route height. In this case, parts of the adjacent rock must also be removed. This is very time-consuming and laborious when driving up the route by hand. The course of the basic route follows the shape of the deposit. In the case of mighty deposits, lying stacks and corridors , the basic route is excavated in the adjacent rock. So that the mine water present in the deposit can be best collected, the basic stretches in the lying area of the deposit are excavated. In narrow aisles, the basic route is driven in the middle of the aisle. Due to this location of the basic route, debris that has deposited on the side cannot be lost.
