Abstract

The invention discloses a combined ultrahigh-lift drainage method and equipment. The equipment is formed by embedding and combining a first-grade drainage system and a secondary relay drainage system, wherein the first-grade drainage system consists of a relay pump (1), a large submersible electric pump (2), a water sucking cover (3), a large drainage pipeline (4) and a large base pipe (5); the secondary relay drainage system consists of a small submersible electric pump (6), a small drainage pipeline (7), a small base pipe (8) and a small elbow (9); the large drainage pipeline (4) of the first-grade drainage system is connected by a flange to be downwards put into the bottom of a mine; a well mouth is fixedly mounted on a well mouth mounting frame (10) by the large base pipe (5); in working, the large submersible electric pump (2) is started firstly; and when the water level in the large drainage pipeline (4) reaches the smallest flooding depth of the small submersible electric pump (6), the small submersible electric pump (6) is started to form the secondary relay drainage system so as to drain mine water to the ground.

Description

technical field [0001] The invention relates to a combined ultra-high-lift drainage method and equipment, which are especially suitable for ultra-deep mine drainage projects. Background technique [0002] my country's mines are generally mined to the deep, and the mining depth of some mines has exceeded 1000m. For such mines, mine drainage has become a technical problem that needs to be solved urgently. The research and development of high-power and ultra-high-lift submersible pumps is an effective way to solve the problem. Due to the limitation of the hydraulic model, increasing the head by blindly increasing the number of series will increase the length-to-diameter ratio of the pump, reduce the stability, and require a lot of manpower and financial resources. Based on this, the present invention proposes a combined ultra-high-lift drainage method and equipment. Utilizing the existing pump-type combined relay drainage, it can not only greatly increase the lift of the mine d...
