摘要(Abstract)：

目前肥城煤田 6 1%的煤炭储量受底板奥陶系灰岩岩溶水威胁 ,采场底板破坏深度的监测是该煤田底板水害防治的重要内容 ,选择肥城煤田曹庄井田 8煤层和 9煤层开采作为监测对象 ,利用向底板岩层注水方法监测岩层破坏情况。利用专利产品“钻孔双端封堵测漏监测仪” ,监测煤层采前的底板原始裂隙发育程度和采后矿山压力底板的破坏深度。监测结果表明 ,8煤层开采造成的底板破坏深度可达 36 .5m ;9煤层开采底板破坏深度可达 14 .2m。
Only the effective water-resisting zone has water-resisting capacity. At present about 61 percent coal reserve in Feicheng coal field is suffering the danger of water-inrush from floor Ordovician karst water while it is mined. Therefore monitor the broken floor depth is a main research project of controlling mine inundation in Feicheng coal field. The being mined coal seam 8 and coal seam 9 of Caozhuang coal mine in Feicheng coal field is selected as the monitor objects. The broken floor can be monitored with infusion method. The stratum original fracture degree before mining coal and broken depth caused by underground pressure can be monitored with the patent ‘Double Ends Sealed Water-loss Monitor’. The research result show that the depth of the broken floor caused by mining coal seam 8 is 36.5 m and the depth of the broken floor caused by mining coal seam 9 is 14.2 m.
