Roof Acquifer Water Inrush Condition In Yu-Shen Mine Area

Yu-Shen Mine Area is known as it's reach resource,excellent mine character and mining condition as well as simple geological structure.However,as the fragile ecological region,the exploitation of the resource has caused a series of ecological problems.Studying on basic theory during coal mining process is the most urgent task in "coal-water" dual-resources mine.This paper task "Yu-Shen Mine Area" as the research object,starting with the coal water relation and water inrush condition,aiming at protecting water resource,the main achievements are as follows:(1)Selecting 410 drills that are distributed on the whole mining area uniformly as the basic data for this study,analyzing coal-water combination;(2)The YuShen Mine Area's coal-water combination are divided into 5 types through SPSS and cluster analysis.(3)By the superposition of water rich and safety of roof caving zoing map through AHP and GIS,The Yu-Shen Mine Area's roof acquifer water inrush are divided into 4 grade,and then the first coal seam's coal seam-aquifers(aquifuge)combination and water inrush risk are discussed.This paper do the research qualitatively and quantificationally,the results have certain reliability,and also provide basis for green mining.
