Hydrodynamic re-commissioning of closed pipe draining system in open pit mining

Authors: Usanov S. V., Melnik V. V., Usanova A. V. 

The closed pipe draining is a part of the complex drainage system arranged on the benches of the upper levels in the Sokolov open pit mine. For 50 years since constructed and placed in service, efficiency of the draining system greatly lowered, which resulted in flooding of the upper benches and increased deformation. In many ways, efficiency of water drawdown reduced because of chocking of drain pipes. The study objects are the difficult segments of the perforated pipes subjected to chocking, and the rates of the drain water flow toward water outlet holes. The aim of the study is to examine mudding of the horizontal pipe drainage, assess the length and frequency of clogs and to estimate the impact of mudding on water flow rates to the outlet holes. The study methods include the geological analysis of the pitwall rock mass in the Sokolov open mine, as well as measurement of drain water flow rates in the draining system before and after hydraulic cleaning of the pipes. As a result of the accomplished research, the mudded sections are located in the pipes, the length of the clogs is determined, the drain pipe capacity is enhanced, and the recommendations are given on maintenance of efficient drainage of the upper levels in the open pit.

Keywords: Aquifer, water inflows, horizontal pipe drainage, water outlet hole, clogs, hydrodynamic washing, open pit mining, deformation of benches in open pits, water content reduction.
