厚婆坳锡矿采空区涌水的封堵

厚婆坳矿全矿分西、中、东三个区段开采,西区已采完,东区为主要出矿区段。由于巷道开拓范围大,井下总涌水量达500～610m~3/h。为了减少矿坑涌水量,需对来自采空区的涌水加以封堵。为此采用构筑隔水墙的方法来减少矿坑总涌水量。文中对隔水墙的设置位置、墙体形状及有关参数、隔水墙结构及原材料、构筑工艺等方面作了阐述。指出这一方法是一种适用经济、简便可靠的有效措施。

SEAL OF WATER FLOW FROM MINED-OUT AREA IN HOUPOAO TIN MINE

The Houpoao tin mine has three mining sections, i.e. the west, the central and the east, with the west section having been mined-out and the east section being the major production area. Because of extensive mine development workings, the total ground water flow rate ranges from 500 to 600 m3/h. For ruduction of the flow rate fron mined-out area, a wallmay be constructed. In the paper, the wall constructing method is discussed including the site shape, relevant parameteras , struc-ture and building materials. Being simple and reliable, the method is a cost effective measure for sealing water flow.
