Description
Technical field
The invention belongs to the hydraulic engineering technical field, particularly structure and the building method on waterproof dam, a kind of dry type tailing disposal sand basis.
Background technology
Tailings Dam refers to build a dam, and the interception mouth of a valley or exclosure consist of, and carries out the place that ore sorts rear discharge mine tailing or other industrial residues in order to store up metal or non-metal mine.Existing Tailings Dam refers to the existing Tailings Dam that has formed.The tails dry discharging is the new Tailings Disposal new technology that recent year rises gradually, its rise mainly is that (the wet type discharge method is that mine tailing is under the slurry state because the existing Tailings Dam of each bargh adopts the wet type discharge method, by pipeline mine tailing from selecting factory to deliver to Tailings Dam, mine tailing in the slurry passes through natural subsidence, be deposited in the Tailings Dam, the water in the slurry selects factory's recycling by naturally clarifying to return again; Adopt the tailings warehouse dam body of the method to be formed by initial dam and late dam, initial dam is to adopt piece stone to build the permeable dike that forms, height is about 10-20 rice, late dam adopts mine tailing to stack and forms, height can reach 100 meters,) storage capacity is full, reached the length of service, continues that discharging can't cause.The wet type discharging is subjected to water level and the big vast needs of reservoir area periphery charge for remittance accent in the storehouse, generally than about the low 1-4 rice of dam body, above space is as regulating and storing storage capacity, to satisfy the safe operation needs for the maximum height that mine tailing is stacked, so below dam body top mark height 1-4 rice is arranged, the storage capacity of 10-20% can not use.Because tailing dam need account for tract, at present expropriation of land is not only very difficult, and invests huge in addition.
Summary of the invention
The purpose of this invention is to provide a kind of water resistance good, the structure on waterproof dam, the robust dry type tailing disposal of dam body sand basis, satisfy the discharging of mine tailing wet type and be about to expiration, change in the tails dry row situation, make dam structure waterproof, integral dam sedimentation, distortion and stability meet the demands.
A further object of the present invention provides the building method of the structure on waterproof dam, a kind of dry type tailing disposal sand basis.
The objective of the invention is to be achieved through the following technical solutions:
The structure on waterproof dam, dry type tailing disposal sand of the present invention basis comprises protocercal tail ore in sand form dam body foundation, it is characterized in that:
