Comprehensive utilization system and utilization method for waste open pit

Abstract

The invention discloses a comprehensive utilization system and utilization method for waste open pit. An artificial gravity dam is built at the middle part of an open pit, and the pit is divided intoan energy conversion utilization area and an oil storage area adjacent to each other; the artificial gravity dam is internally provided with a drainage pipeline, a hydroelectric power generation equipment and a water suction pump are reasonably distributed in the energy conversion utilization area on one side of the artificial gravity dam in a gathering manner, a potential energy is used for generating electricity, and an electric energy can be converted to the potential energy again through the water suction pump, so that energy conversion and storage in various forms are realized; an oil tank is stored at an oil tank placement stratum below the ground surface of the oil storage area on one side of the artificial gravity dam of the pit, so that alternate rapid input storage and extrusionof water and oil can be realized, full utilization of the open pit is realized, the investment and land resource loss of building an oil storage place on the ground are reduced, and meanwhile, the safety of an oil storage system is improved. The comprehensive utilization system and utilization method are low in cost of required materials, good in operability, small in engineering quantity of wholeconstruction, short in construction period and lower in required cost.

Description

technical field [0001] The invention relates to a comprehensive utilization system and method, in particular to a comprehensive utilization system and method for abandoned open-pit pits, belonging to the field of open-pit mining. Background technique [0002] Open-pit mining refers to the process of removing the covering on the ore body resources and extracting useful minerals from the mining field on the open surface. During the mining process, as the ore body is continuously mined, the open-pit mine will form a land area. Huge, deep pits. Surface mining is widely used in the mining industry because of its high mining efficiency, high degree of mechanization, and strong safety. [0003] By the end of 2017, there were a total of 439 open-pit coal mines across the country. Among them, there are about a dozen open-pit coal mines that have been closed, and about thirty open-pit mines that are facing closure. Most of them are inclined and sharply inclined deep concave open-pi...

Problems solved by technology

The most direct way to deal with these open-pit pits is to fill them with soil. However, the amount of landfilling and burial of open-pit mines is large, time-consuming, and expensive, and it is difficult to bury them after the pit is closed; Govern and utilize, but there are still some major bottlenecks that cannot be overcome
