摘要
某磷矿试验盘区以残留矿柱作为空区的支撑体系,随着暴露时间的延长出现矿柱破坏情况,为防止严重灾害出现,开展了空区处理工作,对残留矿柱进行回采,并对空区的周边区域进行了综合地压活动监测,为矿柱回采过程中的科学决策提供了有力的依据,保障了矿柱回采作业的顺利进行。
A phosphate's experiment plot uses the residual pillar as supporting system of goaf,there have been some damages on pillar as time goes on,in order to prevent serious disasters,we carried out goaf management,abstracted the residual pillar,and installed a ground pressure monitoring system surround the goaf,provides powerful basis for scientific decision of pillar stoping process,and ensuring the smooth progress of the abstraction of pillar.
