| 摘 要： | 砖庙硼矿区二人沟矿段是以裂隙含水层充水为主、水文地质条件中等的大型矿床。在矿床充水诸多因素中,发现矿井水害的主要隐患为二人沟小溪地表水沿谷中1号塌陷或未来可能产生的塌陷区涌入矿井,从而提出了该溪流局部改道的防治淹井措施。

THE DEPOSIT'S WATER-FILLED CHARACTER AND THE PREVENTION AND CURE OF SHAFT SUBMERGENCE FOR THE ERRENGOU SECTION OF ZHUANMIAO BORON MINING DISTRICT IN LIAONING |

| Abstract: | The Errengou section of Zhuanmiao boron mining district is a large boron deposit,with mainly water-filling stratum of the water-bearing fissure and moderatehydrologic condition.The folds,faults,brooklets and abandoned pits in the sectiongenerally have less effect on the water-filling of the deposit.The two accidents ofshaft submergence happened since its being put into production in 1973,resultedrespectively from Erengou brooklet pouring down to the goave through the No.1collapse without ore column,and the water gushing caused by water-rich fissureswhich were confronted while water-releasing way were operated.The major hiddendanger of shaft submergence in the section is the No.1 collapse and its nearby latentcollapse areas.Therefore,it has been suggested in this paper that Erengou brookletshould be locally diverged to avoid similar accidents. |
