摘要：
Rich in coal and lack of water is a remarkable characteristic of mining area in western China. The water storage technology of underground reservoir has become an important means of water resources protection in mining area of western China, and the cutting depth of artificial dam plays an important role in the design of underground reservoir. In order to study the influence of cutting depth of artificial dam on the stability of underground reservoir, the MB-1 dam of No. 2 reservoir in Wulanmulun mine is selected as the research object. The 3D calculation model is established by using FLAC3D, and several calculation schemes are made by changing the cutting depth of side, roof and floor, respectively. Then the influence of cutting depth of artificial dam on the stability of mine underground reservoir is deeply analyzed from the aspects of displacement field and stress field. The results show that the optimum cutting depths of MB-1 artificial dam in side, roof and floor are 0.6m, 0.5m and 0.4m, respectively.
