Abstract

Abstract: Through the site monitoring of 506 stope mining pressure in 124 0 m middle-section of Shuiyindong Gold Mine, graph of 506 stope pressure with working time and working face advance was drawn and analyzed, compared and studied, mine pressure change law of 506 stope was revealed, 6 m was the most length of working face advance confirmed. Numerical simulation and stope support economic comparing were done on 506 stope combined with geological data using FLAC software, making sure that the 6m was the safe spacing in production as well as reducing cost greatly.

Key words: Mine pressure monitoring, Numerical simulation, Mine pillar spacing
