摘 要:突水是矿山的主要灾害之一,矿井突水一般来势凶猛,常会在短时间内淹没坑道,给矿山生产带来危害,造成人员伤亡。在富水的岩溶水充水的矿区及顶底板有较厚高压含水层分布的矿山区,在构造破碎的地段,常易发生矿井突水。但只要查明水文地质条件,采取措施,矿井突水是可以预防和治理的。山东霄云煤矿1313工作面突水水量大,而工作面无钻孔,两顺槽掘进中发现的9条断层也不导水,判断不是钻孔、断层导水。突水事故发生后,通过水位、水温及水质化验分析,确定为奥灰水,导水通道为隐伏陷落柱。通过对突水点进行盖帽封堵、对突水通道进行注浆封堵,有效地封堵了过水通道,并满足了《煤矿防治水细则》的要求。Water gushing is one of the main disasters in the mine.It happens fiercely,and often in a short period of time will flood the mining gallery,leading damage to mine production and casualties.In water⁃rich karst water⁃filled mining areas and the mining areas where thick and high⁃pressure aquifers are distributed in the roof and the floor formation,water gushing is prone to happen.However,as long as the hydrogeological conditions are identified and the relevant measures are taken,water gushing in the mine can be prevented and treated.Water gushing was encountered with a large volume at the 1313 working face of Shandong Xiaoyun Coal Mine where there were no boreholes in the working face,and the nine faults discovered in the excavation of the two parallel channels also didn’t conduct water.Analysis of the water level,water temperature and water quality confirmed that it was the ordovician limestone water and the water channel was the hidden collapse column.By capping the water gushing point and grouting the water gushing passage,the water gushing passage was effectively blocked,and the results met the requirements of“Detailed rules for water prevention and control in coal mines”.
