摘要：上白土灣子鐵礦位于肅南裕固族自治縣（簡稱肅南縣），地處祁連山中西部，屬溫帶大陸性氣候區(qū)。礦床主要充水來源為頂、底板基巖裂隙水及構(gòu)造破碎帶裂隙水，水量貧乏，水文地質(zhì)條件和水文地質(zhì)勘探類型均屬簡單型。本文結(jié)合礦區(qū)水文地質(zhì)條件，預(yù)測礦坑涌水量，然后提出礦坑涌水防治建議，以期為礦區(qū)生產(chǎn)提供基礎(chǔ)保障。

Abstract： The Shangbaituwanzi Iron Mine is located in Sunan Yugu Autonomous county （referred to as Sunan county）， in the central and western part of the Qilian Mountains， and belongs to the temperate continental climate zone. The main sources of water filling in the ore deposit are the fissure water in the top and bottom bedrock， as well as the fissure water in the structural fracture zone， and the water volume is poor， and the hydrogeological conditions and exploration types belong to the simple type. Based on the hydrogeological conditions of the mining area， this paper predicts the water inflow of the mine pit， and then proposes suggestions for the prevention and control of water inflow in the mine pit， in order to provide a basic guarantee for the production of the mining area.

Keywords： hydrogeology; water inflow of mine pit; prevention and control; Shangbaituwanzi Iron Mine; Sunan county
