Abstract

The invention provides a precipitation system and a construction method thereof. The precipitation system comprises a plurality of precipitation wells, the precipitation system further comprises drainage wells, and the drainage wells communicate with the precipitation wells, so that liquid in the precipitation wells is collected to the drainage wells and discharged through the drainage wells. Theprecipitation system solves the problem that all precipitation wells of dewatering wells in a strip mine precipitation system of the prior art needs to be drained by drainage pumps.

Description

technical field [0001] The invention relates to the technical field of mine drainage, in particular to a dewatering system and a construction method of the dewatering system. Background technique [0002] At present, the drainage wells of open-pit mines use one pump for each well, and each well includes power supply lines and water supply pipelines. The investment cost and daily maintenance cost are high. Each well involves electromechanical operation and management, and daily inspections are time-consuming and laborious. , the dewatering well cannot be tested for relevant parameters during operation, and the operating status of each well can only be judged initially by the amount of water supplied. The water output capacity of the dewatering well also brings about the problem of pump selection in the later stage. The number of water pumps is very large, and every well must be observed daily to avoid problems that cannot be detected in time due to problems with the precipita...
