含水老窿区下部开采隔水方法探讨

Contains water lower part the old hole area to mine separates thewater method discussion

含水老窿区下部开采隔水方案一直未能确定,暂留1个中段做保安矿柱,给矿石的安全高效回收带来不利影响。通过调查,确定了无矿段隔水范围,无须构筑专门的隔水工程;参照国内矿山经验及有关标准,分别采用废石胶结体、保安矿柱隔水。在无水害的采场进行不同结构体隔水试验,以求得工艺简单、经济合理、安全可靠的隔水方案。

Contains water lower part the old hole area to mineseparates the water plan not to be able to determine that, holds 1center-section to make the security ore stone column, brings theadverse effect for the ore security highly effective recycling. Through the investigation, had determined non- ore Duan Geshui thescope, does not need to construct special separates the water project; Refers to the domestic mine experience and the related standard, separately uses the scrap rock cemented body, the security ore stonecolumn separates the water. Picks the field in the non- flood to carryon the different structure body to separate the water test, the craftsimple, the economy reasonable, is in order to safe reliably separatesthe water plan.
