Description

A kind of branch drop shaft unloads ore deposit device
Technical field
The present invention relates to a kind of drop shaft and unload ore deposit device, particularly a kind of branch drop shaft unloads ore deposit device, belongs to technical field of ore extraction.
Background technology
Mine chute utilizes ore to conduct oneself with dignity in underground mining operation it to be collected the conventional facility of haulage to end level by high level, usually, the extracted ore in each stage (or segmentation) is transferred by branch's drop shaft and is pooled to main chute, then by transport, lifting means, ore is transported to earth's surface.
Main chute is one of most important engineering of underground metal mine, and underground mining ore out all needs through this collection storage and transhipment, and whether unimpeded its safety and stability run is on mining production impact greatly.In actual mining production process, the deformation failure of main chute is common phenomenon, its main cause is except the engineering geological conditions of present position own is (as Surrounding Rock Strength, zone of fracture, the problems such as water), outside the impact of neighbouring adjacent engineering, shock loading is also very important destructive factor, especially ore comes together in the process of main chute through each branch drop shaft, the lower curved section connected with main chute due to branch's drop shaft makes ore drawing flow direction and main chute axially in certain angle of cut, and ore has the initial velocity of certain horizontal direction when departing from branch's drop shaft, thus after causing ore to enter main chute, inevitably impact on certain height of drop the main chute of limited section to wall, it is caused to be subject to impact failure, and the branch's drop shaft be positioned on main chute wall exports the erosion damage slump expansion that are constantly subject to motion ore stream, thus cause its top unstability, be caving destruction gradually, and expand to periphery gradually, so that form larger slump dead zone, even extend through other engineering of periphery, thus normal transport and the production safety of ore is had a strong impact on.
The method of dealing with problems at present mainly increases the diameter of branch's drop shaft ore discharging port bottom main chute section of being hit, safe chamber is set, full well ore drawing, improve support material intensity and adopt rail and steel plate to strengthen the impact resistance of main chute wall in the main chute section of being hit, these measures respectively have quality, increase diameter and safe chamber is set and can solve impact failure problem to a certain extent, but because ore fragmentation differs greatly, when departing from branch's drop shaft outlet, under identical horizontal initial rate, due to its mass discrepancy, the impact site height of ore to main chute wall of different lumpiness has larger difference, to carry out expanding to main chute in a big way or safe chamber is set, increase engineering quantity on the one hand, its supporting difficulty will be increased on the other hand, the impact load that the mode adopting rail and steel plate to strengthen the impact resistance of main chute wall in the main chute section of being hit can delay main chute wall destroys, but poor actual field Use Limitation fruit, and itself is equally comparatively subject to destruction, and slack time is extremely limited, full well ore drawing has the effect protecting drop shaft preferably, and Problems existing is comparatively large on production capacity impact, difficult management.
Summary of the invention
The object of the present invention is to provide a kind of branch drop shaft to unload ore deposit device, this device can avoid ore destroy the shock loading of main chute wall and destroy the polish-brush of the main chute wall in branch's drop shaft exit.
