摘要
“双层水位”开采方法是近几年提出的防水、防塌、安全、经济的矿山开采方法。本文从分析裂隙-岩溶介质的渗透性特点及渗透性随深度的变化规律着手,并引用湖南省辰溪煤矿大坪井田近年来深部开采所形成的双层水动力状况方面的资料,论述了南方大水岩溶矿区利用“双层水位”开采方法的可行性。
The 'double elevation' is a waterproof, anti-collapsing, safe and economical means of mine development recently suggested. This paper starts from an analysis of the permeability characteristics of the fissured-karst media and the law of variation of permeability with depth, utilizing informations of double elevation water fluctuations formed by recent deep-excavations of Chenshi coal mine in Hunan province, the feasibility of the 'double elevation' method of coal mining in the abundant water bearing Karst mines in south China is discussed.
