深埋土岩接触带下导水裂隙带发育规律
DEVELOPMENT RULES OF WATER FLOWING & FRACTURE ZONE AT DEEP BURIED SOIL-ROCK INTERFACE DURING MINING
摘要
Abstract
This paper aims to find the reason for preventing the crushing and water inrush accidents under deep buried soil-rock interface at coal mine in Eastern China.It analyses the geological environment of fractured rock mass with high water pressure under deep buried sand-sandstone interface.It uses the measured data including the height of water flowing fractured zone and simple hydrological observations data of drilling hole.It examines the development rules of the height of water flowing fractured zone during mining under deep buried soil-rock interface using principal component analysis.The results show that:ratio of the height of water flowing fractured zone and mining thickness and waterproof coal pillar fits Boxlucas1 exponential function model.The thickness of weathered zone inhibits the height of water flowing fractured zone to some extent.But for the sand-sandstone interface,as the presence of adown penetration zone,the inhibitory effect of weathered rock on the height of water flowing fractured zone increases.关键词
