Segmented drainage method of open pit mine

Abstract

The invention discloses a segmented drainage method of an open pit mine. An open pit bottom water sump (6) is arranged at the open pit bottom, and an immersible pump (1) is arranged on an open pit platform above the open pit bottom water sump (6). The segmented drainage method is characterized in that a chamber (8) is horizontally constructed on an open pit platform side slope (10) above the position of a conventional fixing pump station water pump (2), and the position of the chamber (8) should avoid faults; a chamber water sump (5) is downward constructed in the chamber (8), and a chamber fixing pump station water pump (3) is installed in the chamber (8); and the immersible pump (1) pumps open pit water catchment which is intensively converged into the open pit bottom water sump (6) intothe chamber water sump (5) in the chamber (8), and then pumps (3) from the chamber fixing pump station water pump (3) to the outside of an open pit. According to the segmented drainage method of theopen pit mine, partial side slope mines can be mined and the ore loss is reduced; and meanwhile, the chamber fixing pump station water pump (3) is not affected by earth surface meteorological conditions, side slope rolling stones and the like, and a fixing pump station water pump house does not need to be built.

Description

technical field [0001] The invention relates to an open-pit mine drainage method, in particular to a segmented comprehensive drainage technology for open-pit mines, which can be widely used in open-pit mine drainage operations, and is especially suitable for large-scale deep concave open-pit bottom drainage. Background technique [0002] Doing a good job in waterproofing and drainage is a prerequisite for ensuring safe production in open-pit mines. In particular, sunken open-pit mines objectively have the conditions to collect atmospheric precipitation, surface runoff and underground water gushing. Therefore, effective waterproof and drainage measures must be taken during the entire production process of the open-pit mine, and even during the infrastructure construction period. [0003] If the gushing water in the open pit cannot be discharged in time, it will not only cause the equipment to be flooded, but also cause other unpredictable consequences and affect the normal pr...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of side slope pressure ore existing in the existing open-pit mine drainage system and the need to build a fixed pump station water pump room, and to provide a side slope that can be mined part of the pressure ore, reduce ore loss, and do not need to build Sectional Drainage Method of Open-pit Mine with Water Pump Room of Fixed Pumping Station
