武山铜矿下向进路充填采矿法采场顶板爆破震动效应研究
Study on the vibration effect of roof in the downward stope drifts of cemented backfill process of Wushan copper mine
【摘要】 为了扩大矿山生产能力,武山铜矿正进行大断面下向进路回采充填工艺和采场结构参数优化的试验研究。使用BlastmateⅢ测振仪对试验采场的充填体顶板进行了4次爆破震动实测,运用线形回归推导出了顶板的最大爆破振速公式,其测试数据和结论对类似矿山有一定的借鉴意义。
【Abstract】 To increase the production capacity,Wushan copper mine is carrying out the optimization research on production technology and structure parameters on the occasion of downward stoping drifts with larger cross sectional area.The paper has tested the vibration effect on the stope roof for four times with Blastmate Ⅲ vibration meter,and concluded the formula of maximum velocity of roof by linear regression.The test data and formula may be helpful in other similar mines.
