Patent number: 9689128Abstract: The present disclosure provides an artificial dam of a distributed coal mine underground reservoir and its constructing method. The artificial dam comprises a support layer (10), an anti-seepage layer (20), and a concrete structure layer (30) that are successively formed in an auxiliary roadway (1) from inside to outside, the concrete structure layer (30) being embedded into a security coal pillar (2) and/or surrounding rock (3) around the auxiliary roadway (1). Because the concrete structure layer (30) is embedded into the security coal pillar (2) and/or the surrounding rock (3) around the auxiliary roadway (1), the artificial dam is combined to the security coal pillar (2) to together form a dam for an underground reservoir. Due to multi-layer design, anti-seepage performance and structural strength of the dam can meet the water storage requirements of the underground reservoir.Type: GrantFiled: April 10, 2014Date of Patent: June 27, 2017Assignee: CHINA SHENHUA ENERGY COMPANY LIMITEDInventors: Dazhao Gu, Quansheng Li, Sushe Chen, Zhiguo Cao
