Zoning and Prevention of Coal Mine Flooding in Guizhou Based on Sedimentary Facies
In order to make macroscopic guidance for flooding prevention and control work in Guizhou coal mines,through the analysis of sedimentary facies and water-rich property of coal measures strata and underlying and overlying strata in Guizhou,it is known that the water-rich property of coal measures strata and adjacent strata in Guizhou is obviously zonated because of the control of sedimentary facies,according to the sedimentary facies,the area of flooding in Guizhou coal mine is divided into three parts:the west,the middle and the west,and the east.In view of the main hidden danger of water disaster in Guizhou coal mines,such as old kiln(emp-ty)water,atmospheric precipitation,surface water,roof(separated layer)water,floor water,etc.,the key points of flooding prevention and control in coal mine are put forward by zoning.The research results can help the coal mine managers to understand the main types of mine flooding from the macro-level,flooding prevention and control work direction,has important practical significance.
