Definitions
- the invention relates to a method for planning Mining operations in a tectonically stressed Sedimentation deposit, in particular Hard coal deposit, by laying down Degradation direction, length, speed and Sequence of dismantling, the location of the mining operations at the tectonic disturbances in the deposit body will and to determine the to dismantle and to be prepared for the laying layer body Delete and the discard size of each recognized geological disturbance as well as the course of the folding energy as well as those caused by the tectonic energy Loosening, bruising and pressing in the mountains and aie thereby influenced tectonic mass transport as Planning basis can be used.
- Such a method is in WO 95/14155 described; in this procedure the tectomechanical process in the formation of the deposit for project planning of the deposit parts taken into account by the tectomechanical relationships when the mining plan is created Deposit body can be used as the basis for the mining planning be made, with more precise information about design and behavior of tectonics the basics of mining planning as well as the associated planning necessary training Improve devices. So with the known Process the relationships between wholesale and retail Small electronics or between initial and subsequent faults already made usable for the dismantling planning. Here allows the consideration of the tectomechanical Relationships an earlier indication of whether for example, discarding a known disorder probably stays the same or in one or the other other stroke direction increases or decreases.
- DE-A-2544391 describes a method for determining the optimal direction of degradation, especially to avoid Mountain strikes, gas eruptions and stone falls are known at which the construction sequence and thus the dismantling taking into account reducing tectonic forces and is carried out, the zones with less reduction the tectonic forces are first reduced separately and the dismantling from zones with greater reduction in the Area with less reduction in tectonic forces to be led.
- the invention is therefore based on the object generic methods with regard to the informative value of To further improve planning principles.
- the basic idea of the invention provides that the planning mining companies depending on the pranks, the Strike length and width of recognized and under Taking into account that by the folding energy and the tectonic energy shaped tectomechanical process projected seam washout in the deposit body be oriented, with the location of spacious Displacements and / or displacement zones under Consideration of an equidistance inherent in the deposit determined and when digging out a seam wash in one Distance of less than 300 m from the painting of the Seam washout determined and in relation to Deletion of the displacement and / or the displacement zone in Energy flow direction is set.
- seam washouts Understanding seam regularities, including seam dust, Seam shipments, seam splitting, seam splitting, lenticular deposits in the seam, fillings of Erosion channels as well as extensive seam erosion count; the problems caused by seam washout in the There are many different types of mining: the salvage in the claim increased, compared Sloping outbreaks are more susceptible to the Result of "removal problems", furthermore the tools wear out on the extraction machines and / or the extraction must be local be switched to blasting. At the same usable Promotion washouts also lead to a higher Recovery and thus to higher necessary dumping capacities over days. Furthermore, seam washings also contribute same usable output of a shaft system to one more exposure to other operating points with higher Progress of dismantling or with the necessary unscheduled investments for additional mining operations; The intended dismantling sequences cannot be adhered to.
- the mountain range is usually at certain intervals due to larger, roughly parallel displacement zones that over paint great distances, in side by side Lanes divided. Doing so on the shifts more or less large horizontal mass transport took place. Depending on the collapse of the mountain strata and depending on the tectonic energy supplied and their local reductions are in tectomechanical Process in the area of the shift zones insignificant With up to significant tectonic disturbances more than 100 m discard.
- Thrusts Based on these relationships in tectomechanical process is between the Displacement zones with larger warps on the jumps to count. Mountain material is reinforced there brought together, so that in such zones the Possibilities of movement on small tectonic disturbances in Mountains are restricted.
- two Thrusts can be on a cross to Generalized lines or a narrow band run out in the same direction; in this case Seam washings that are in the direction of the line or the paint a narrow band when planning the Orientation of mining operations to be taken into account.
- this applies to seam washouts that occur in the Outflow area of thrusts located to the south start and about 400 m before the north of it Expire thrust.
- the early later energy differences in the tectomechanical process out The same applies if striking east-west Shifts or striking north-south Southward shifts in the same area leak.
- the leakage of wrinkles and Change of importance insofar as north of the Outflow area seam seams with north-south Swipe in the western outlet area and with east-west painting in the eastern outlet area planning must be taken into account.
- the bisector between two is emerging and deleting about parallel thrusts with a Discard dimension of more than 10 m when planning Mining operations to be considered.
- seam washouts are up to one bankable distance of approx. 400 m on the slope of Thrusts also in planning the orientation to be involved by mining operations; it refers to Seam washout parallel to the thrust to brush. It is essential that the Thrusts in the north and south wings of large Saddle systems are located and facing north and south come to mind; here were due to the stress distribution in the tectomechanical process the later tensions relative low and this created a free space for possible areas of weakness in which seam washout occurs formed.
- the hanging area of thrusts is during the tectomechanical process through shift sliding claimed. This is related to changes in the Thrust measure at the thrust in the same stratigraphic level; in these cases the Shift sliding the areas with seam washout stronger destroyed, and because of this, after one Embodiment of the invention, the mining planning to provide for the expansion distance in the route area reduced and the expansion delay in the longwall area are reduced.
- the petrography of the deposit is of importance; powerful Point sandstone banks a short distance from a seam for near-shore sedimentation, and in this area the tectonic movements were probably less; Seam washout in connection with movements Weakness zones have been left out.
- mining planning does not need to consider seam washout to take; however, with such Measures to adapt mining operations a lesser thickness with a larger one Adjustment range of the longwall construction and with a suitable one Winning funds are provided.
