METHOD FOR CONTROL OF ROCK PRESSURE Russian patent published in 1997 - IPC

Abstract RU 2081316 C1

FIELD: mining industry. SUBSTANCE: for control of rock pressure at mine field boundary in edging part of displacement sincline, mining of ore is effected by alternating long and short chambers. If extraction drift is located perpendicularly to mine field boundary, length of short chambers is increased as their location is moving towards boundary of edging part of displacement sincline closer to complete extraction zone. If positioning of extraction drift is parallel to mine field boundary, short chambers extend to boundary of stepped relieving zone. EFFECT: high efficiency. 3 dwg
