Deep mine water supply pressure reduction and stabilization control technology

Abstract

Abstract:

Comprehensive solution of multiple horizontal water supply and low level water supply overpressure was indicated. Numerical modeling analysis of pipeline pressure fluctuation was carried out by hydromechanics software. By comparing fluid field pressure fluctuation, the fluctuation was controlled less than 20% of normal flow rate. The result of numerical modeling provided theoretical basis for selection of valve pressure rating and closing time. Fluctuation of water flow in pipeline was eliminated. Leakage of working face water supply system connections was eliminated.

Key words:

mine, water supply, pressure reduction, constant pressure, numerical modeling
