Definitions

• the invention relates to a method for planning mining operations in a tectologically stressed sedimentation deposit, in particular hard coal deposit, by determining the direction of mining, the length of mining, the speed and rate of the mining, the location of the mining bed being oriented towards the tectonic disturbances in the body of the mine and for determining the extent to which mining takes place. and the depository body to be prepared includes the incidence, the deletion and the degree of rejection of the respective identified geological disturbance as well as the course of the folding energy as well as the loosening, squeezing and pressing in the mountains caused by the tectonic energy and the tectonic mass transports influenced thereby as a basis for planning.
• the tectomechaic relationships allows an earlier indication as to whether, for example, the rejection of a known disorder is likely to remain the same or whether it increases or decreases in one or the other strike direction determine and draw conclusions for the dismantling planning; it is possible to provide information on the cracking of cracks depending on the collapse of the mountain strata, i.e. depending on the state of the unfolding, and to align the mining planning with this. This also enables more precise information on the design and behavior of large and small electronics to be provided, which in some cases has already improved the basics for mining planning and thus mining planning itself in a goal-oriented manner.
• the known method has already improved planning security for the orientation of mining operations in a depository body, further problems in connection with rock in the flozing area occur during mining or extraction, which often lead to a reduction in the operating point requirement and the abandonment of the corresponding one Building height.
• the invention is therefore based on the object of further improving the generic method with regard to the significance of the planning principles
• the basic idea of the invention provides that the degradation bed to be planned depends on the
• the term "river leaching” is understood to mean regularity of the seam, for which seam dusting, seaming, seam formation, seam splitting, lenticular embedding in the seam, fillings in erosion channels as well as shallow float erosion, which are many problems in the extraction caused by seam leaching.
• the salvage is increased in the demand, there is a greater susceptibility to sloping outbreaks with the consequence of "expansion problems", furthermore the tools on the extraction machines wear out and / or the extraction must be converted locally to blasting.
• leaching also leads to a higher amount of mountains and thus to higher necessary Haid capacities for days.
• floc wash-out also leads to a higher loading of other operating points with higher mining progress or with the necessary unscheduled investments for additional mining beds, planned mining sequences cannot be adhered to.
• the invention is essentially associated with the advantage that the above-mentioned difficulties can be largely avoided by omitting areas with stronger or frequent washouts for the orientation of mining operations.
• the position of large-scale displacements and / or displacement zones is determined taking into account an immunity distance from the storage facility and, when digging out a river washout at a distance of less than 300 m therefrom, the removal of the river washout is determined and in relation to the strikeout of the Shift and / or the shift zone is set in E ⁇ ergiehnet ⁇ chtung.
• the mountains are generally divided into adjacent paths by larger, roughly parallel displacement zones that span large distances. A more or less large horizontal mass transport has taken place at the displacements.
• the distance between large, east-west-facing main shifts is latent can and are usually designed as Schwachezone ⁇ , about 5.2 km; in between there are further displacement zones or displacements at a distance of 0.8 to 1.5 km, depending on the reduction in folding energy.
• Shifting zones can be reckoned with larger warps on the jumps.
• mountain materials are increasingly brought together so that the movement possibilities of small-tectonic disturbances in the mountains are restricted in such zones.
• the deletion direction of dominant displacements or displacement zones in a deposit depends on the reduction in the folding energy in large saddle and displacement areas. Stronger unfoldings and / or overshoot dimensions are associated with a large reduction in tectonic energy. In the direction of energy flow, this creates different energy contents side by side. The greater energy is diagonally deflected towards the lower energy. In this direction (strike direction) there are shearings, which are responsible for the development and configuration of shifts in the tectomechanical process; the fraying was created early and can be described as the protrusion of the mountains.
• the river washouts are projected, and the direction of breakdown of the mine bed to be oriented is determined in each case parallel to the projected river washout.
• the middle bisector between two collapses that are roughly parallel in incidence and strike with a warping dimension of more than 10 m must be taken into account when planning mining operations.
• the stresses of the mountains are superimposed when the banking distance of the thrust is less than 800 m; these 800 m are important in the case of the Ruhr cabon in that this distance is a significant distance between large tectonic thrusts in some areas of the Ruhr cabon.
• river leaching up to a banking distance of approx. 400 m in the slope of thrusts should also be included in the planning of the orientation of mining companies; these are seam washouts that strike parallel to the thrusting.
• the mining planning has to provide that the removal distance in the route area is reduced and the expansion delay in the longwall area is reduced.
• the petrography of the deposit is also important; powerful sandstone banks at a short distance from a seam indicate sedimentation close to the shore, and in this area the tectonic movements were probably less; Lump erosion in connection with movements in weak areas has not occurred.
• the mining plan does not need to consider seam To take washes, however, in such circumstances, measures must be taken to adapt the mining bed to a lower thickness with a larger adjustment range of the longwall construction and with a suitable means of extraction.
