Shale gas flowback sewage treating system

Abstract

The invention discloses a shale gas flowback sewage treating system. The sewage treating system comprises reserve ore blocks and a water pump water absorption tube, stoping ore blocks are arranged onone sides of the reserve ore blocks, a mining tunnel is arranged on the periphery of the reserve ore blocks, one sides, far away from the reserve ore blocks, of the stoping ore blocks are provided with water drainage pipes, a ventilation pipe is arranged above the stoping ore blocks, the water drainage pipes are arranged above both the stoping ore blocks and the reserve ore blocks, a water sump isarranged below the stoping ore blocks, a water sump water inlet pipe is arranged on the front surface of the water sump, a liquid level detector is arranged on one inner side of the water sump, and awater sump protection net is arranged close to a position above the liquid level detector inside the water sump; workers passing the periphery of the water sump can be conveniently protected by the water sump protection net, the problem of safety accidents caused by too deep water of the water sump is avoided, meanwhile, ore falling into water can be convenient to clear, the problems that stonesfalling into the water are difficult to clear and influence the water storage of the water sump are avoided.

Description

technical field [0001] The invention belongs to the technical field of mining, and in particular relates to a shale gas flowback sewage treatment system. Background technique [0002] Mining engineering is divided into coal mines and non-coal mines. Mining (English name: ore mining) is the technology and science of mining mineral resources from the earth's crust or surface. Generally refers to the mining of metal or non-metallic deposits. In a broad sense, mining also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. Mining industry is an important raw material extraction industry, such as metal ore is the main raw material of metallurgical industry, non-metallic ore is chemical raw material and building materials, coal and oil are important energy sources. Most ores need to be enriched by beneficiation before they can be used as industrial raw materials. [0003] The existing drainage device fo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a shale gas flowback sewage treatment system to solve the problem that the existing mining drainage device proposed in the above background technology is poor in safety when used, and the staff is easy to fall into the water tank of the drainage device when not paying attention At the same time, the large ore falling into the water tank will easily affect the water storage capacity of the water tank, which is not convenient for the normal drainage of the mine, and it is not convenient for the workers to carry out the construction safely, and the direct one-time drainage method requires a large pump power The problem
