大面积含水层下的矿体开采

MINING OF OREBODY BENEATH LARGE-AREA AQUIFER

水口山矿务局康家湾矿区的主要矿体埋藏深度大,并合低温热水,其上部覆盖着与湘江洪泛区有天然水力联系的大面积含水层,开采难度很大,是典型的水体下开采的矿山.本文介绍了该矿区首采地段采矿方法的选择,采场构成要素的确定,采准工程的布置,回采与充填工艺的实施,采场地压观测的方法及效果,对类似的矿山有借鉴作用.

The depth of main orebody with low temperature and warm water in Kangji-awan mine.Shuikoushan Bureau of Mine, is great. The top of this orebody was covered with the large-area aquifer with a natural hydraulic relation to the flooding area of Xiang River. The mining is very difficult, and it is a typical mine of underwater mining. The au-thor makes an introduction to constitution parameters of stope in mining district, selection of mining methods for the first mining section, arrangement of development work and en-forcement of mining and filling technology as well as method and result of ground-pressure observation of stope. These measwres provide a reference for the similar mines.
