The invention provides a gob-side entry retaining light-weight high-strength concrete block wall and a construction technology thereof and discloses a mining roadway light-weight concrete block wall supporting process. The mining roadway light-weight concrete block wall supporting process is characterized in that no coal pillars is remained, a roadway-side supporting wall building mode is formed through block ground prefabricating and underground manual building, the roadway-side wall is implemented stepwise segment by segment along with propulsion of a stope face, and a shelter support or a suspension support is adopted on the goaf side for temporary supporting. Compared with the prior art, the mining roadway light-weight concrete block wall supporting process has the advantages of being good in supporting effect, easy to implement and the like.
