摘要
Abstract
Zhangjiamao Coal Mine contains 5 layers of coal seam .The research of the height of water flowing fractured zone in coal working face has important significance for the prediction of water inflow and water source protection of Changjiagou reservoir.By the actual detection in №15204 fully mechanized mining face , the height of water flowing fractured zone is 65.10~69.17m.The water flowing fractured zone of 4-2 coal seam has extended to the surface in local area .The water flowing fractured zone of 5-2 coal seam has extended to 4-2 coal seam floor , to soil layer in thin bedrock area near valley ex-tends and to the surface in local area .Although water content of each aquifer is extremely weak , the goaf water may cause harm to the mine after multi-coal seam mining .关键词
