摘要： An improved system and method for relocating a selected layer of overburden, such as a layer of unconsolidated soil, in a strip mining operation are provided. The system employs an excavator, an intermediate belt wagon with at least two slewable conveyors, and a cross-pit conveyor having a long cantilevered conveyor pivotably supported on a mobile base; with all of said equipment being preferably based on the highwall side of the pit. According to the method, the area to be stripped is divided first into a series of large rectangles aligned parallel to the pit, with each rectangle being further divided into a series of narrow strips also parallel to the pit. The area is then progressively stripped beginning with the nearest strip of a first rectangle and proceeding with the next adjacent strip until the first rectangle is completed and then proceeding in like manner with each successive rectangle. The excavated material is transferred via the belt wagon and cross-pit conveyor directly across the pit and redistributed there in slightly curved windows which simulate the pattern according to which it was excavated.

摘要： A strip mining technique wherein an active mining area is continuously moved across a mining ground. In one form of the invention, overburden is removed from a leading end of the active mining area and conveyed by a conveyor system located on a highwall of the mining area to a following end of that mining area. The conveyed overburden is dumped adjacent the active mining area following end to form a spoil bank which is landscaped and reclaimed. Another form of the invention includes a conveyor system located on the main bench.

摘要： An underground mining method for unexploited coal in a boundary open-pit mine is provided. A shaft construction platform is arranged at one rock step to two rock steps above a coal seam. Intermediate bridges are built starting from a pit bottom. Mining area clay is laid on a working slope where no intermediate bridge is built and on a side slope with an outcrop of the coal seam as a sealing layer to seal the slopes. Auxiliary vertical shafts and main inclined shafts are dug. The pit bottom is dug downward to form a digging space on a side close to the working slope between two adjacent ones of the intermediate bridges, and clay is filled into the digging space to form an artificial water barrier layer. A roadway communicating the main inclined shafts and the auxiliary vertical shafts is constructed, and a coal seam stope face is arranged.

摘要： A dumping system, for the dumping of material, in particular for the filling of a former strip mine, includes a conveyor belt with belt modules (7) suspended on cables and a traveling tripper (15), which is arranged traveling in the direction of conveying. The belt modules (7) are fastened by braced carrier cables (3) and suspension cables (5) fastened thereto in a mostly horizontal alignment. The traveling tripper (5) can travel on the belt modules (7). Furthermore, the slack of the carrier cables (3) may be compensated by a different length of the suspension cables (5), such that the belt modules (7) are aligned mostly horizontally. It is thus possible to span over the area to be dumped (for example, a pit) with cables and to dump material by means of the traveling tripper at all points of the bracing. Thus, it is not necessary to drive the dumped material.
