金河磷矿马槽滩矿区大巷突水原因及防治措施剖析

ANALYSIS OF THE ROADWAY WATER INRUSH REASON IN MACAOTAN MINING AREA IN JINHE PHOSPHATE DEPOSIT AND PREVENTION MEASURES

金河磷矿马槽滩矿区大巷出现涌水,严重影响了勘查施工与矿山的正常生产。矿区主要充水因素为断裂、构造裂隙充水,主要岩溶含水层及大气降水也对矿床充水有一定影响。F22断裂及破碎带与地表汇水区三道沟联通,突水主要是掘进F22含水断层破碎带引起。今后在采掘探矿过程中遇到断层时要坚持"有疑必探,先探后掘,疏堵结合,分类防治"的原则,采取疏水降压和注浆改造相结合的方法解决问题,防治突水事故。

The roadway of Macaotan mining area in Jinhe phosphate deposit appears gushing, seriously affected the construction of survey and the mine normal production. The main factor in water-filled mine is fracture and structural cracks filled with water, The main karst aquifer and precipitation also have some impact on the water-filled deposit. F22 fault and fracture zones connect Sandaogou surface catchment area, Water inrush is mainly caused by boring F22 fault fracture zone. We encountered faults in mining exploration in the future should adhere to the principle of ＂ the suspects will be exploration, first exploration after excavation, the combination of dredge and containment, classification Prevention＂, take the method of hydrophobic buck and grouting reconstruction combined to solve the problem, preventing water inrush.
