Abstract:

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” .

Key words:mine water gushing;grouting to stop water;collapse column;ordovician limestone;water cut-off wall
