摘要
Abstract
Through the rational design of mine pressure observation scheme, a careful analysis of mine pressure monitoring data, determine the first caving step distance is 18m, which belongs to the 2B class medium stable roof, roof first weighting step distance 42m, pressure strength obviously belongs to grade II roof; according to the analysis of monitoring data rules and ultra distance before maintenance suggest greater than 25m; the initial and periodic weighting take small progress multi cycle mode.关键词
