内蒙古翁牛特-库伦一带严重缺水区找水研究

翁牛特-库伦一带为西辽河平原周边的严重缺水区,区内地形、地貌及地质构造条件复杂,找水难度较大.在该区找水过程中充分利用了前人资料,综合研究区域水文地质条件及地下水的补径排规律,合理采用遥感、物探等各方面的新技术、新方法.主要寻找断层带脉状水、碳酸岩类裂隙溶洞水、古河道砂砾石松散岩类水等.通过两年的工作,为地方成井7眼,总涌水量达3464.91m³/d,缓解了部分地区的人畜饮用水紧张状况,起到了典型的示范作用.

A STUDY ON GROUNDWATER- SEARCHING IN THE ONGNIUD- KULUN REGION,INNER MONGOLIA

The Ongniud Kulun region in the southwest of West Liaohe River plain is in serious short of water.It is difficult to search groundwater in the region for its complex conditions of terrain,physiognomy and geologic structures.In the groundwater searching practice,we necessarily studied previous data,synthetically analyzed the hydrogeologic conditions and the rules of groundwater recharge,flowthrough and drainage,and adopted new techniques and methods such as remote sensing and geophysics. It is important to probe groundwater in faulted zones,the fissures or caves of carbonate rocks,the incompact and porous beds of paleochannel.Through two years'work,7 wells have been finished for the local government.The flow yield of the groundwater amounts to 3464.91 m3/d,which alleviates the serious condition of daily used water for human and livestock in the regions.The work has established a typical model of seeking water in similar regions.
