Mine wastewater treatment method and system for upfill mining

Abstract

The invention discloses a method and system for treating waste water of a mine suitable for upward filling and mining. The system comprises a centralized transportation mechanism, a vertical discharge mechanism and a horizontal flow guide mechanism. The centralized transportation mechanism comprises an ore drift canal (3) and a transverse drift canal (4), and the ore drift canal (3) and the transverse drift canal (4) are located below a mining area and communicated with each other; the vertical discharge mechanism comprises a main drain hole (5) and a main line drain hole (12), a stoping roadway (1) is communicated with the ore drift canal (3) through the main drain hole (5), and a mining preparation roadway (2) is communicated with the transverse drift canal (4) through the main line drain hole (12); the horizontal flow guide mechanism comprises a drain tank (8), a water filtration retaining wall (9) and a water pump (10), the drain tank (8) is arranged in the stoping roadway (1) and communicated with the main drain hole (5), a water inlet of the water pump (10) is arranged in the water filtration retaining wall (9) on the lower portion of the stoping roadway (1), and a water outlet of the water pump (10) is arranged in a main line canal (11). The system is high in treatment capacity, high in efficiency and low in energy consumption and applied to treating waste water of the mine suitable for upward filling and mining.

Description

technical field [0001] The invention belongs to the technical field of mining engineering infrastructure, and in particular relates to a mine wastewater treatment method and system which are simple in structure, easy to implement, low in construction cost, high in treatment efficiency and suitable for upward filling mining. Background technique [0002] Mining engineering is an important basic industrial project for the development of my country's modern industry. With the rapid development of the national economy, the scale of the mining industry has been further expanded to a large extent. In the process of mine mining, the water flowing into the mine from various sources, or the water flowing through the mine drainage system is called mine water. Mine water mainly comes from atmospheric precipitation, surface water, aquifer water, fault water and old empty water. In mines mined by water and sand filling method and hydraulic mining method, mine water also includes some oth...

Problems solved by technology

However, for mining areas with long mining roadways, in order to save engineering effort and shorten infrastructure construction time, a layered filling mining structure arranged obliquely downward is generally adopted. The wastewater treatment method in this structure must be drained by area and section. At present, in the existing wastewater treatment system, the combination of self-flowing ditch and water pump drainage cannot meet the requirements of efficient treatment, and the treatment time is long and the effect is not ideal.
