Description
Technical field
The utility model belongs to the mine safety technical field, relates to a kind of staged mine tailing storehouse device that drains off floodwaters.
Background technology
The mine tailing storehouse is the association of the various structure of the mine tailing that produces behind the safe storage mine ore dressing.The security and stability in mine tailing storehouse depends primarily on two aspects: the firstth, and the security and stability of tailing dam; The secondth, the security and stability of the system of drainning off floodwaters.According to statistics, China's nonferrous metal mine causes 50% of the whole mine tailing storehouse accident that almost accounts for of disaster because of the system's accident of drainning off floodwaters.Therefore scientific and reliable is set drains off floodwaters that to get rid of the flood in mine tailing storehouse swimmingly most important for the security and stability in mine tailing storehouse for system, safety.
The main flow pattern in China mine tailing storehouse is mountain valley-type mine tailing storehouse, and if mine tailing storehouse can not satisfy the production length of service and require the time, general and tailing storehouse, the follow-up storehouse of taking over is not in lining, a mountain valley (or coombe).But factors such as the landform of being subjected to, geological conditions, production management, cost of production restrict, make several mine tailing storehouses in a mine understand stepped being distributed in same mountain valley or the coombe, such mine tailing storehouse is called " staged mine tailing storehouse ", the cascade development power station of some similar water electric system.The characteristics in staged mine tailing storehouse are to be distributed successively from high to low along landform by the independent mine tailing storehouse more than 3 and 3 to form, and advantage is to maximally utilise the natural storage capacity that mountain valley (or coombe) forms; Centralized arrangement is convenient to production management simultaneously.
Pipe laying under the dam that the many employings of the pattern of drainning off floodwaters in staged mine tailing storehouse are at present got in touch continuously, all there is the pipe that drains off floodwaters separately in every storehouse, the flood in storehouse, upstream flows into the storehouse, middle reaches by the pipe that drains off floodwaters, compile the drain off floodwaters pipe of back by the storehouse, middle reaches with the flood in storehouse, middle reaches and enter the storehouse, downstream, the flood in final upstream, middle reaches, three storehouses, downstream gathers the back and all is discharged into mountain valley, downstream (or coombe) by the pipe that drains off floodwaters in storehouse, downstream.
There is following drawback in this mode of drainning off floodwaters:
1, drain off floodwaters the load repeat the stack.The flood that its storehouse, upstream is discharged has all been born in storehouse, every downstream, past more downstream, and the pressure that drains off floodwaters is layering greatly more, has repeated to increase the load that drains off floodwaters in every mine tailing storehouse, makes the system engineering of drainning off floodwaters of staged mine tailing storehouse drop into strengthen.
2, drain off floodwaters and have a big risk.At present the system of drainning off floodwaters in staged mine tailing storehouse is contact continuously, if fault has appearred in the pipe that drains off floodwaters in wherein any storehouse, the safety that all can influence self storehouse, place and other storehouses is drained off floodwaters, and then staged mine tailing storehouse all can be absorbed in breakneck situation.
3, the big section pipe safety reliability that drains off floodwaters is lower.Loading because drain off floodwaters is layering, and makes past more downstream, and the flow that drains off floodwaters is big more, and the cross dimension of respective row water pipe is big more.Owing to covering reasons such as the mine tailing load is big, construction quality is not good enough on the pipe that drains off floodwaters, causing the big section pipe damage accident generation frequency of drainning off floodwaters is that the nonferrous metal mine mine tailing storehouse accident rate of drainning off floodwaters in the structure is the highest, and up to more than 60%, safety reliability is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of staged mine tailing storehouse device that drains off floodwaters, and this device can overcome the defective of existing apparatus, and safety is drained the flood in staged mine tailing storehouse, thereby ensures the safety in mine tailing storehouse.
The technical solution of the utility model is: device drains off floodwaters in a kind of staged mine tailing storehouse, this staged mine tailing storehouse comprises the independent mine tailing storehouse more than 3 or 3, more than independent mine tailing storehouse distribute successively from high to low, this device comprises staged mine tailing storehouse, regulating dam, master drain off floodwaters facility, the system of drainning off floodwaters.The main facility inlet that drains off floodwaters is located at the regulating dam side and walks around staged mine tailing storehouse from a side, extends to the downstream.Trips three storehouses in upper, middle and lower are drained separately in the storehouse flood and are all adopted the system of drainning off floodwaters, the system of drainning off floodwaters respectively with lead the facility that drains off floodwaters and join.Described regulating dam is to be arranged in upstream, staged mine tailing storehouse.
The utility model has following advantage: 1, regulating dam and the main facility that drains off floodwaters play " cutting flood " effect jointly, the flood (generally accounting for more than the 60%-70% of the total catchment area in staged mine tailing storehouse) of the above catchment area of regulating dam was drained with regard to interception before entering the mine tailing storehouse, extenuate the pressure that drains off floodwaters in the mine tailing storehouse greatly, helped the safety and stability in mine tailing storehouse.2, this part flood of directly being drained by regulating dam and the main facility interception of drainning off floodwaters does not enter the mine tailing storehouse thereby not by tailings pollution, the shunting that realized removing contamination helps environmental protection.3, after the interception shunting, the flood discharge that enters in the mine tailing storehouse significantly reduces, thereby three mine tailing storehouses are drained the system's cross dimension of drainning off floodwaters of flood in the storehouse separately and can correspondingly be significantly reduced, reduced the system of drainning off floodwaters by on cover mine tailing load weight and the risk of damaging, improved the safety reliability in the system of drainning off floodwaters and mine tailing storehouse.4, flood in the storehouse is independently drained separately in three mine tailing storehouses, and the stack that repeats of the load of having avoided drainning off floodwaters makes storehouse, every downstream no longer bear the load that drains off floodwaters in its storehouse, upstream, has overcome to have " tandem " drain off floodwaters deficiency of device now; Simultaneously the system of drainning off floodwaters in every storehouse all is relatively independent, and its risk of drainning off floodwaters is no longer changeed and added to adjacent mine tailing storehouse, thereby has greatly improved the drain off floodwaters safety reliability of system of whole staged mine tailing storehouse.
