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 (), an anti-seepage layer (), and a concrete structure layer () that are successively formed in an auxiliary roadway () from inside to outside, the concrete structure layer () being embedded into a security coal pillar () and/or surrounding rock () around the auxiliary roadway (). Because the concrete structure layer () is embedded into the security coal pillar () and/or the surrounding rock () around the auxiliary roadway (), the artificial dam is combined to the security coal pillar () 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.
